March 2, 2026 - Spanish Mountain Gold Receives Positive Particle Ore Sorting Results for the Phoenix Deposit Highlighting Production Upside

https://spanishmountaingold.com/news/2026/spa...on-upside/

Spanish Mountain Gold has achieved highly positive results in Phase 1 XRT ore sorting tests for its Phoenix deposit, showing potential to double ROM feed grades while rejecting 50%–70% of waste mass. Tests show 85%–92% gold recovery, with Phase 2 bulk sample testing underway for a 2026 economic study.

XRT Ore Sorting Progress (Phoenix Deposit)

Key Results: Tests conducted by ABH Engineering and the Saskatchewan Research Council (SRC) using Tomra XRT equipment indicated that the material is highly amenable to sorting.

Performance Metrics: The technology successfully upgraded the material from an average grade of 0.48 g/t to over double the grade, while rejecting 50% to 70% of the feed mass, and recovering 85% to 92% of the gold.

Phase 2 Testing: Following positive Phase 1 results, Phase 2 is evaluating 100-kg bulk samples in parallel with the Main deposit, aimed at optimizing sorting algorithms.

Strategic Impact: The initiative aims to significantly reduce the size of the proposed mill and lower initial capital expenditure (CAPEX) for the project, with results likely to be incorporated into an updated economic assessment in 2026.

Technology Partners & Future Plans

Partners: ABH Engineering Inc. and OrePortal Technologies Ltd. are working on particle and bulk sorting analysis.

Goal: The company aims to make a construction decision in 2027 by enhancing project economics through enhanced feed grades

October 20, 2025 - Spanish Mountain Gold Initiates X-ray transmission (“XRT”) Ore Sorting Work on Gold Mineralization

https://spanishmountaingold.com/news/2025/spa...alization/

Spanish Mountain Gold Ltd. (“Spanish Mountain” or the “Company”) (TSX-V: SPA; FSE: S3Y; OTCQB: SPAUF) is pleased to announce the commencement of a particle ore sorting program with ABH Engineering Inc. and a bulk ore sorting study with OrePortal Technologies Ltd. ABH previously completed amenability tests on the mineralization from the Main deposit that indicated positive results with X-ray transmission (“XRT”) ore sorting to increase process plant mill feed grades and gold produced while targeting lower costs and improved project economics for the Spanish Mountain Gold (“SMG”) project (see January 21, 2025 news release).

OrePortal will assess if the run of mine mineralized material, prior to crushing, is suitable for ore sorting. If the assessment is successful, a material reduction of the size of the proposed mill and initial capex will be assessed.

President and CEO, Peter Mah, stated, “The amenability of the SMG project gold mineralization to XRT ore sorting is an exciting new opportunity for the project. Ore sorting is anticipated to improve the project scale and economics while derisking portions of the resource, especially lower grade feed. Preconcentrating mineralization essentially moves more gold through the process plant, which could dramatically uplift processed grades, gold production and overall project economics. This initiative is part of a multi-pronged strategy to uplift lower grade portions of the resource and improve gold production during the first ten years of the proposed PEA life of mine. We see this as an important step to complete as we advance the project towards the feasibility study and ultimately a build decision by or in 2027.”

Particle Ore Sorting Studies (ABH)

There are numerous benefits to ore sorting for the SMG project, and it is an important, potential improvement to the run of mine (“ROM”) feed grade of the process plant that could result in higher metal production, lower operating capital per tonne processed, and higher metal recoveries post processing. Particle Ore Sorting can also aid in the rejection of barren material that leads to the reduction of fine tailings, reduced materials handling charges for transportation, reduced process plant and tailings capital expenditures, and ultimately, lower impact to the local receiving environment through reduced water, reagents and overall infrastructure footprint.

The Company is proposing to undertake particle ore sorting test work that will benefit from the results from an earlier study on the Main deposit completed with ABH (see January 21, 2025 news release). The proposed work program will create multiple products and algorithms to determine the optimal sorting conditions for achieving the highest possible increase to gold recovered per tonne milled through the processing plant.

The company is proceeding with sample collection from the historical drill core at the project site. Samples for this testing will be from both Phoenix and Main deposits that provides a more direct comparison of future production results through the evaluation of the particle ore sorting performance under economic assumptions, and it shall include the development of both capital and operating expenditure estimates.

It is anticipated that this important work could find additional gold ounces that could enhance the project economics from the recent PEA (see July 3, 2025 news release). The SMG project can be scalable to meet higher production levels that with the ore sorting will match throughput for the Process Plant.

Bulk Ore Sorting (OrePortal)

The bulk ore sorting study will evaluate its amenability to the SMG project by examining several key factors that include determining the presence of ore heterogeneity. The study will also evaluate what are the preferred sensors for the ore by examining the suitability of the sensor configuration for SMG project. OrePortal employs a desktop study methodology to ascertain if further laboratory work is warranted.

The heterogeneity of the mineralization is studied through the assessment of gold distribution using the 3D block model and assay geochemistry from the recent mineral resource estimate (“MRE”) from the recent PEA (see July 3, 2025 news release). With respect to sensors, XRF and Prompt Gamma Neutron Activation Analysis (“PGNAA”) will be reviewed using suitable models of proxy elements that the sensors can detect to select a suitable model that can be used to classify ore by gold content. Examples of bulk ore sorting systems include bucket mounted XRF sensors or belt-mounted PGNAA sensors affixed to conveyor belt systems.

From the analysis, OrePortal will look to provide estimates of the capital and operating expenditures required and study the impact to the net present value of the project against the recent PEA (see July 3, 2025 news release).

What is sensor-based ore sorting?

Sensor-based ore sorting is a mineral pre-concentration technology in which particles of material are separated based on some physical or chemical property as measured or inferred by a sensor.

It is used to upgrade process feed by identifying and rejecting waste material early in the mining process which results in pre-concentration of valuable materials into a lower gross volume.

Ore sorting exploits the variability of the orebody, which in many cases is overlooked for higher volumes of feed material.

Types of ore sorting sensors

Several variables are considered when choosing an appropriate sensor for a sorting system. These include, but are not limited to, the ore mineralogy, the ore heterogeneity, the feed method, the throughput rate, and the required accuracy.

This is because different sensors have different depths of penetration, applicable size distributions, abilities to identify versus quantify ore properties and accuracies based on the target material and their specific operating parameters.

Sensing technologies that have been applied in various sensor-based ore sorting processes include:

X-ray transmission (XRT) – classifies ores according to their atomic density

X-ray fluorescence (XRF) – measures elemental abundance based on fluorescence under x-rays

Prompt Gamma Neutron Activation Analysis (PGNAA) and Pulsed Fast Thermal Neutron Activation (PFTNA) – measures elemental abundance based on gamma ray signatures from scattering events.

Colour camera – classifies industrial minerals, base- and precious-metal ores or gemstones by colour, reflection, brightness, and transparency

Laser – measures reflection, adsorption, and fluorescence of the laser light on crystal structures

Near-Infrared and Infrared (NIR/IR) – classifies and quantifies ore mineralogy according to their associated reflection, absorption, and transmission spectrum profile

Hyperspectral – classifies ores according to spectral signature across a range of visible, near infrared and short, mid, and long wave infrared bands

Magnetic Resonance (MR) – a form of radiofrequency (RF) spectroscopy that is used for quantitative measurement of target ore minerals

Laser-induced breakdown spectroscopy (LIBS) – detects elemental composition through the analysis of spectral signatures generated from high intensity laser pulses

Electromagnetic (EM) – classifies metals and ores in accordance with their conductivity and permeability.

The system and algorithms that convert the data into information used to make sorting decisions is just as critical as the sensor. Speed, accuracy, resolution, volume limitations, and detection limits of such systems are key considerations that will impact sensor selection.

Depending on where the sensing technology is positioned in the process chain and the capability of the sensor itself, additional process steps may need to be added to present the material in a specific way or divert material after it has been sensed. This includes additional equipment such as grizzlies, feeders, sizers, diverters, and conveyors.

Benefits of sensor-based ore sorting

Primary benefits obtained from ore sorting vary based on individual mine characteristics, but generally result in more metal production at a lower cost and lower environmental footprint.

Benefits may include:

Unlocked plant capacity - through earlier rejection of waste material prior to processing

Increased plant head grade - by replacing rejected waste or low grade with higher grade material in the processing plant

Reduced cost per metal unit produced - through the increase in metal produced due to higher grade feed and the reduction in costs associated with processing waste or lower grade material

Reduced tailings volume - rejecting waste from ore at an early stage allows the mass of fine final tailings to be reduced and the associated storage space

Reduced carbon emissions, water and energy consumption - rejecting waste before the processing plant and upgrading the plant feed means less tonnes of ore treated in the processing plant per ton of product. This results in reduced water usage, energy consumption and subsequent carbon emissions per metal unit produced

Increased mineable reserves - rejecting waste from run of mine ore enables mining with a lower cut-off grade and a corresponding increase in mine life

Reclaimed ore from dumps and low grade stockpiles - bulk ore sorting (or particle sorting) may enable the recovery of valuable components from waste dumps, low-grade stockpiles and marginal reserves that would otherwise be uneconomic to treat

Reduced dilution and ore loss - if applied at the mining face bulk ore sorting can reduce dilution and ore loss

Optimized capital spend - in brownfields operations capital for plant upgrades can be delayed or eliminated. For greenfield operations, plant size can be reduced, or the production rate increased

Summary
=========

XRT technology (X-Ray Transmission) is expected to lower the capital expenditure (Capex) for Spanish Mountain Gold's project by potentially reducing the size of the proposed mill and initial capex. By sorting ore before it enters the mill, the company can reduce the amount of material that needs to be processed, which could allow for a smaller and less expensive processing plant.

XRT ore sorting reduces operating costs in gold production by separating valuable ore from waste rock early in the process. This process, called pre-concentration, significantly increases the grade of the material sent to the mill. This leads to lower costs in several areas, including less material needing to be mined, transported, crushed, and processed, which in turn decreases energy and water consumption, reagent use, and the amount of fine tailings requiring storage. Ultimately, it results in a higher grade of feed going to the processing plant, improving overall economic potential and reducing the environmental footprint.

Reduced plant size: XRT ore sorting can increase the grade of the mill feed, meaning a smaller mill can process the same amount of gold. A smaller mill would result in lower initial capital costs for construction.

Lower overall plant costs: Besides the initial capital, the technology could also lead to lower overall costs due to a smaller footprint and reduced materials handling.

Future assessment: Spanish Mountain Gold is currently assessing the suitability of their ore for this technology, and a successful assessment could lead to a material reduction in the size of the proposed mill and initial capex.

==================================
How XRT ore sorting increases gold grade
==================================

Sensor-based separation: XRT sensors analyze the density of rocks as they pass along a conveyor belt. They can identify and differentiate between dense, gold-bearing ore and lighter waste rock.

Targeted ejection: The system uses a high-speed air jet to eject the waste rock or lower-grade ore, while the higher-grade material is sent on to the processing plant.

Pre-concentration: This initial sorting step effectively "pre-concentrates" the ore, meaning that only the material with a higher concentration of gold is sent for further, more expensive milling and processing.

===========================
Benefits of using XRT ore sorting
===========================

Higher mill feed grade: By removing waste rock, the average grade of the ore fed into the mill increases significantly. For example, tests have shown increases of 39% for gold and 47% for silver.

Lower costs: Processing a smaller volume of higher-grade ore leads to lower processing costs for grinding, flotation, and other stages.

Reduced environmental footprint: Discarding a large portion of waste rock early reduces the amount of tailings, water usage, and energy consumption for the entire operation.

Improved project economics: The combination of higher grade, lower costs, and increased production efficiency can dramatically improve project economics, including increased IRR and faster payback periods.

Increased recovery: While not all gold is recovered in the sorting step, the material that is sorted has a much higher grade, leading to higher overall project recovery rates.

2025年10月20日 - 西班牙山黄金启动金矿化X射线透射(“XRT”)矿石分选工作

https://spanishmountaingold.com/news/2025/spa...alization/

西班牙山黄金 欣然宣布,该公司已与 ABH工程公司 启动一项颗粒矿石分选项目,并与 OrePortal技术公司 启动一项批量矿石分选研究。ABH此前已对主矿床的矿化进行了适应性测试,结果表明,X射线透射(“XRT”)矿石分选取得了积极成果,可提高选矿厂的进料品位和黄金产量,同时降低成本,提高西班牙山金矿的项目经济效益。金矿(“SMG”)项目(参见2025年1月21日新闻稿)。

OrePortal 将评估破碎前的矿化材料是否适合进行矿石分选。如果评估成功,将评估拟建选矿厂规模和初始资本支出的大幅缩减。

总裁兼首席执行官Peter Mah表示:“SMG项目金矿化可采用XRT矿石分选技术,这对项目来说是一个激动人心的新机遇。矿石分选预计将提升项目规模和经济效益,同时降低部分资源的风险,尤其是低品位给矿。预选矿本质上是将更多的黄金输送到选矿厂,这可以显著提高选矿品位、黄金产量和项目整体经济效益。这项举措是我们多管齐下战略的一部分,旨在提升低品位资源部分,并在拟议的初步经济评估矿山寿命的前十年提高黄金产量。我们认为这是推进项目可行性研究并最终在2027年或之前做出建设决策的重要一步。”

颗粒矿石分选研究 (ABH)

矿石分选对 SMG 项目有诸多益处,它对选矿厂的原矿(“ROM”)品位具有重要的潜在改善作用,可以提高金属产量,降低每吨矿石的运营成本,并提高选矿后的金属回收率。颗粒矿石分选还可以帮助剔除贫矿,从而减少细尾矿,降低运输过程中的物料处理费用,减少选矿厂和尾矿的资本支出,并最终通过减少用水量、试剂用量和整体基础设施的占用空间,降低对当地接收环境的影响。

公司拟开展颗粒矿石分选试验,该试验将借鉴此前与ABH公司合作完成的一项关于主矿床的研究成果(参见2025年1月21日的新闻稿)。拟议的工作方案将创建多种产品和算法,以确定最佳分选条件,从而最大限度地提高选矿厂每吨矿石的黄金回收率。

公司正在项目现场从历史钻芯中采集样品。此次测试的样品将来自Phoenix和Main矿床,通过在经济假设下评估颗粒矿石分选性能,可以更直接地比较未来的生产结果,并将包括资本和运营支出的估算。

预计这项重要工作将发现更多金矿,从而提升近期初步经济评估(参见2025年7月3日的新闻稿)中的项目经济效益。SMG项目可扩展以满足更高的产量,通过矿石分选,其产量将与选矿厂的产量相匹配。

散装矿石分选 (OrePortal)

散装矿石分选研究将通过考察几个关键因素(包括确定矿石异质性的存在)来评估其与SMG项目的适应性。该研究还将通过考察传感器配置与SMG项目的适用性,评估哪些传感器是矿石的首选传感器。 OrePortal 采用桌面研究方法来确定是否有必要进行进一步的实验室工作。

矿化非均质性研究通过使用三维块体模型评估金的分布,并结合近期初步环境评估(PEA)中的最新矿产资源估算(“MRE”)的地球化学分析结果进行研究(参见2025年7月3日的新闻稿)。在传感器方面,我们将使用传感器能够探测到的替代元素的合适模型,对XRF和瞬发伽马中子活化分析(“PGNAA”)进行审查,以选择合适的模型,用于根据金含量对矿石进行分类。散装矿石分选系统的示例包括安装在铲斗上的XRF传感器或固定在传送带系统上的带式PGNAA传感器。

根据分析结果,OrePortal将估算所需的资本和运营支出,并根据近期的初步环境评估(PEA)研究其对项目净现值的影响(参见2025年7月3日的新闻稿)

什么是基于传感器的矿石分选?

基于传感器的矿石分选是一种矿物预浓缩技术,其中根据传感器测量或推断的一些物理或化学特性来分离材料颗粒。

它通过在采矿过程的早期识别和剔除废料来提升工艺进料,从而将有价值的物料预先浓缩到较小的体积中。

矿石分选利用了矿体的多变性,而这在很多情况下会被大量进料所忽视。

矿石分选传感器的类型

在为分选系统选择合适的传感器时,需要考虑多个变量。这些变量包括但不限于矿石的矿物学、矿石的异质性、进料方式、吞吐率和所需的精度。

这是因为不同的传感器具有不同的穿透深度、适用的粒度分布、识别和量化矿石特性的能力,以及基于目标物料及其特定操作参数的精度。

已应用于各种基于传感器的矿石分选工艺的传感技术包括:

X射线透射 (XRT) – 根据矿石的原子密度对其进行分类

X射线荧光 (XRF) – 根据X射线下的荧光测量元素丰度

瞬时伽马中子活化分析 (PGNAA) 和脉冲快热中子活化 (PFTNA) – 根据散射事件产生的伽马射线特征测量元素丰度。

彩色相机——根据颜色、反射率、亮度和透明度对工业矿物、贱金属矿石、贵金属矿石或宝石进行分类

激光——测量激光在晶体结构上的反射、吸收和荧光

近红外和红外 (NIR/IR)——根据矿石相关的反射、吸收和透射光谱特征对其进行分类和量化

高光谱——根据可见光、近红外以及短波、中波和长波红外波段的光谱特征对矿石进行分类

磁共振 (MR)——一种射频 (RF) 光谱技术,用于定量测量目标矿石矿物

激光诱导击穿光谱 (LIBS)——通过分析高强度激光脉冲产生的光谱特征来检测元素组成

电磁 (EM)——根据金属和矿石的电导率和磁导率对其进行分类。

将数据转化为用于分选决策的信息的系统和算法与传感器同样重要。此类系统的速度、精度、分辨率、容量限制和检测限是影响传感器选择的关键因素。

根据传感技术在工艺链中的位置以及传感器本身的性能,可能需要添加额外的工艺步骤,以特定方式呈现物料或在感测后进行分流。这包括额外的设备,例如格筛、给料机、分级机、分流器和输送机。

基于传感器的矿石分选的优势

矿石分选的主要优势因矿山特性而异,但通常能够以更低的成本和更少的环境足迹提高金属产量。

优势可能包括:

释放工厂产能——通过在加工前尽早剔除废料

提高工厂原矿品位——通过在加工厂中用更高品位的原料替代被剔除的废料或低品位原料

降低单位金属生产成本——通过提高原料品位来增加金属产量,并降低与加工废料或低品位原料相关的成本

减少尾矿量——在早期阶段从矿石中剔除废料,可以减少细粒最终尾矿的质量,并节省相关的储存空间。

减少碳排放、水和能源消耗——在选矿厂前剔除废料并升级选矿厂进料,意味着每吨产品在选矿厂处理的矿石吨数更少。这可以减少用水量、能源消耗以及随之而来的每单位金属的碳排放量。

增加可采储量——从原矿中剔除废料,可以降低边界品位,从而延长矿山寿命。

从废料堆和低品位矿堆回收矿石——散装矿石分选(或颗粒分选)可以从废料堆、低品位矿堆和边际储量中回收有价值的成分,而这些成分的处理成本原本是不经济的。

减少贫化和矿石损失——如果在采矿工作面应用散装矿石分选,可以减少贫化和矿石损失。

优化资本支出——在棕地运营中,可以推迟或取消工厂升级的资本投入。对于新建项目,可以缩小工厂规模或提高生产率。

摘要
======

XRT(X射线透射)技术有望降低西班牙山黄金公司项目的资本支出(Capex),其潜在优势在于能够缩小拟建选矿厂的规模并降低初始资本支出。通过在矿石进入选矿厂之前进行分选,该公司可以减少需要处理的物料量,从而建造规模更小、成本更低的选矿厂。

​​

XRT矿石分选技术通过在生产过程早期将有价矿石与废石分离,降低了黄金生产的运营成本。这一过程被称为预选,能够显著提高送入选矿厂的物料品位。这在多个方面降低了成本,包括减少了需要开采、运输、破碎和处理的物料量,进而降低了能源和水的消耗、试剂的使用以及需要储存的细尾矿量。最终,它提高了送入选矿厂的原料品位,提升了整体经济效益并减少了对环境的影响。

缩小选矿厂规模:XRT矿石分选技术可以提高选矿厂原料的品位,这意味着可以用更小的选矿厂处理相同数量的黄金。规模较小的工厂可以降低建设的初始资本成本。

降低工厂整体成本:除了初始投资外,该技术还能因占地面积更小、物料搬运量更少而降低整体成本。

未来评估:西班牙山地黄金公司目前正在评估其矿石是否适用于该技术,如果评估成功,则有望大幅减少拟建选矿厂的规模和初始资本支出。

===========================
XRT矿石分选如何提高黄金品位
===========================

基于传感器的分离:XRT传感器分析岩石在传送带上的密度。它们能够识别并区分高密度含金矿石和较轻的废石。

定向喷射:该系统利用高速气流喷射废石或低品位矿石,而高品位物料则被送往选矿厂。

预浓缩:这一初始分选步骤有效地对矿石进行“预浓缩”,这意味着只有含金量较高的物料才会被送往后续成本更高的选矿和加工工序。

=======================
使用 XRT 矿石分选的优势
=======================

提高磨机进料品位:通过去除废石,入磨矿石的平均品位显著提高。例如,试验表明,金矿石的平均品位提高了39%,银矿石的平均品位提高了47%。

降低成本:处理较少量的高品位矿石可降低磨矿、浮选和其他阶段的加工成本。

减少环境足迹:及早丢弃大量废石可减少整个作业的尾矿量、用水量和能耗。

提高项目经济效益:更高的品位、更低的成本和更高的生产效率相结合,可以显著提高项目经济效益,包括提高内部收益率 (IRR) 和缩短投资回收期。

提高回收率:虽然并非所有黄金都能在分选步骤中回收,但分选出的矿石品位更高,从而提高项目的整体回收率。

2025年10月20日 - 西班牙山黄金啟動金礦化X射線透射(“XRT”)礦石分選工作

https://spanishmountaingold.com/news/2025/spa...alization/

西班牙山黄金 欣然宣布,該公司已與 ABH工程公司 啟動一項顆粒礦石分選項目,並與 OrePortal技術公司 啟動一項批量礦石分選研究。ABH 此前已對主礦床的礦化進行了適應性測試,結果表明,X射線透射(“XRT”)礦石分選取得了積極成果,可提高選礦廠的進料品位和黃金產量,同時降低成本,提高西班牙山金礦的項目經濟效益。金礦(“SMG”)項目(參見2025年1月21日新聞稿)。

OrePortal 將評估破碎前的礦化材料是否適合進行礦石分選。如果評估成功,將評估擬建選礦廠規模和初始資本支出的大幅縮減。

總裁兼首席執行官Peter Mah表示:“SMG項目金礦化可採用XRT礦石分選技術,這對項目來說是一個激動人心的新機遇。礦石分選預計將提升項目規模和經濟效益,同時降低部分資源的風險,尤其是低品位給礦。預選礦本質上是將更多的黃金輸送到選礦廠,這可以顯著提高選礦品位、黃金產量和項目整體經濟效益。這項舉措是我們多管齊下戰略的一部分,旨在提升低品位資源部分,並在擬議的初步經濟評估礦山壽命的前十年提高黃金產量。我們認為這是推進項目可行性研究並最終在2027年或之前做出建設決策的重要一步。”

顆粒礦石分選研究 (ABH)

礦石分選對 SMG 項目有諸多益處,它對選礦廠的原礦(“ROM”)品位具有重要的潛在改善作用,可以提高金屬產量,降低每噸礦石的運營成本,並提高選礦后的金屬回收率。顆粒礦石分選還可以幫助剔除貧礦,從而減少細尾礦,降低運輸過程中的物料處理費用,減少選礦廠和尾礦的資本支出,並最終通過減少用水量、試劑用量和整體基礎設施的佔用空間,降低對當地接收環境的影響。

公司擬開展顆粒礦石分選試驗,該試驗將借鑒此前與ABH公司合作完成的一項關於主礦床的研究成果(參見2025年1月21日的新聞稿)。擬議的工作方案將創建多種產品和算法,以確定最佳分選條件,從而最大限度地提高選礦廠每噸礦石的黃金回收率。

公司正在項目現場從歷史鑽芯中採集樣品。此次測試的樣品將來自Phoenix和Main礦床,通過在經濟假設下評估顆粒礦石分選性能,可以更直接地比較未來的生產結果,並將包括資本和運營支出的估算。

預計這項重要工作將發現更多金礦,從而提升近期初步經濟評估(參見2025年7月3日的新聞稿)中的項目經濟效益。SMG項目可擴展以滿足更高的產量,通過礦石分選,其產量將與選礦廠的產量相匹配。

散裝礦石分選 (OrePortal)

散裝礦石分選研究將通過考察幾個關鍵因素(包括確定礦石異質性的存在)來評估其與SMG項目的適應性。該研究還將通過考察傳感器配置與SMG項目的適用性,評估哪些傳感器是礦石的首選傳感器。 OrePortal 採用桌面研究方法來確定是否有必要進行進一步的實驗室工作。

礦化非均質性研究通過使用三維塊體模型評估金的分布,並結合近期初步環境評估(PEA)中的最新礦產資源估算(“MRE”)的地球化學分析結果進行研究(參見2025年7月3日的新聞稿)。在傳感器方面,我們將使用傳感器能夠探測到的替代元素的合適模型,對XRF和瞬發伽馬中子活化分析(“PGNAA”)進行審查,以選擇合適的模型,用於根據金含量對礦石進行分類。散裝礦石分選系統的示例包括安裝在鏟斗上的XRF傳感器或固定在傳送帶系統上的帶式PGNAA傳感器。

根據分析結果,OrePortal將估算所需的資本和運營支出,並根據近期的初步環境評估(PEA)研究其對項目淨現值的影響(參見2025年7月3日的新聞稿)

什麼是基於傳感器的礦石分選?

基於傳感器的礦石分選是一種礦物預濃縮技術,其中根據傳感器測量或推斷的一些物理或化學特性來分離材料顆粒。

它通過在採礦過程的早期識別和剔除廢料來提升工藝進料,從而將有價值的物料預先濃縮到較小的體積中。

礦石分選利用了礦體的多變性,而這在很多情況下會被大量進料所忽視。

礦石分選傳感器的類型

在為分選系統選擇合適的傳感器時,需要考慮多個變量。這些變量包括但不限於礦石的礦物學、礦石的異質性、進料方式、吞吐率和所需的精度。

這是因為不同的傳感器具有不同的穿透深度、適用的粒度分布、識別和量化礦石特性的能力,以及基於目標物料及其特定操作參數的精度。

已應用於各種基於傳感器的礦石分選工藝的傳感技術包括:

X射線透射 (XRT) – 根據礦石的原子密度對其進行分類

X射線熒光 (XRF) – 根據X射線下的熒光測量元素豐度

瞬時伽馬中子活化分析 (PGNAA) 和脈沖快熱中子活化 (PFTNA) – 根據散射事件產生的伽馬射線特征測量元素豐度。

彩色相機——根據顏色、反射率、亮度和透明度對工業礦物、賤金屬礦石、貴金屬礦石或寶石進行分類

激光——測量激光在晶體結構上的反射、吸收和熒光

近紅外和紅外 (NIR/IR)——根據礦石相關的反射、吸收和透射光譜特征對其進行分類和量化

高光譜——根據可見光、近紅外以及短波、中波和長波紅外波段的光譜特征對礦石進行分類

磁共振 (MR)——一種射頻 (RF) 光譜技術,用於定量測量目標礦石礦物

激光誘導擊穿光譜 (LIBS)——通過分析高強度激光脈沖產生的光譜特征來檢測元素組成

電磁 (EM)——根據金屬和礦石的電導率和磁導率對其進行分類。

將數據轉化為用於分選決策的信息的系統和算法與傳感器同樣重要。此類系統的速度、精度、分辨率、容量限制和檢測限是影響傳感器選擇的關鍵因素。

根據傳感技術在工藝鏈中的位置以及傳感器本身的性能,可能需要添加額外的工藝步驟,以特定方式呈現物料或在感測后進行分流。這包括額外的設備,例如格篩、給料機、分級機、分流器和輸送機。

基於傳感器的礦石分選的優勢

礦石分選的主要優勢因礦山特性而異,但通常能夠以更低的成本和更少的環境足跡提高金屬產量。

優勢可能包括:

釋放工廠產能——通過在加工前盡早剔除廢料

提高工廠原礦品位——通過在加工廠中用更高品位的原料替代被剔除的廢料或低品位原料

降低單位金屬生產成本——通過提高原料品位來增加金屬產量,並降低與加工廢料或低品位原料相關的成本

減少尾礦量——在早期階段從礦石中剔除廢料,可以減少細粒最終尾礦的質量,並節省相關的儲存空間。

減少碳排放、水和能源消耗——在選礦廠前剔除廢料並升級選礦廠進料,意味著每噸產品在選礦廠處理的礦石噸數更少。這可以減少用水量、能源消耗以及隨之而來的每單位金屬的碳排放量。

增加可採儲量——從原礦中剔除廢料,可以降低邊界品位,從而延長礦山壽命。

從廢料堆和低品位礦堆回收礦石——散裝礦石分選(或顆粒分選)可以從廢料堆、低品位礦堆和邊際儲量中回收有價值的成分,而這些成分的處理成本原本是不經濟的。

減少貧化和礦石損失——如果在採礦工作面應用散裝礦石分選,可以減少貧化和礦石損失。

優化資本支出——在棕地運營中,可以推遲或取消工廠升級的資本投入。對於新建項目,可以縮小工廠規模或提高生產率。

摘要
======

XRT(X射線透射)技術可望降低西班牙山黃金公司專案的資本支出(Capex),其潛在優勢在於能夠縮小擬建選礦廠的規模並降低初始資本支出。透過在礦石進入選礦廠之前進行分選,該公司可以減少需要處理的物料量,從而建造規模更小、成本更低的選礦廠。

該 XRT礦石分選技術透過在生產過程早期將有價礦石與廢石分離,降低了黃金生產的營運成本。這個過程稱為預選,能夠顯著提高送入選礦廠的物料品位。這在多個方面降低了成本,包括減少了需要開採、運輸、破碎和處理的物料量,進而降低了能源和水的消耗、試劑的使用以及需要儲存的細尾礦量。最終,它提高了送入選礦廠的原料品位,提升了整體經濟效益並減少了對環境的影響。

縮小選礦廠規模:XRT礦石分選技術可以提高選礦廠原料的品位,這意味著可以用更小的選礦廠處理相同數量的黃金。規模較小的工廠可以降低建設的初始資本成本。

降低工廠整體成本:除了初始投資外,該技術還能因佔地面積較小、物料搬運量較少而降低整體成本。

未來評估:西班牙山地黃金公司目前正在評估其礦石是否適用於該技術,如果評估成功,則有望大幅減少擬建選礦廠的規模和初始資本支出。

===========================
XRT礦石分選如何提高黃金品位
===========================

基於感測器的分離:XRT感測器分析岩石在傳送帶上的密度。它們能夠識別並區分高密度含金礦石和較輕的廢石。

定向噴射:此系統利用高速氣流噴射廢石或低品位礦石,而高品位物料則被送往選礦廠。

預濃縮:這一初始分選步驟有效地對礦石進行“預濃縮”,這意味著只有含金量較高的物料才會被送往後續成本更高的選礦和加工工序。

=======================
使用 XRT 礦石分選的優勢
=======================

提高磨機進料品位:通過去除廢石,入磨礦石的平均品位顯著提高。例如,試驗表明,金礦石的平均品位提高了39%,銀礦石的平均品位提高了47%。

降低成本:處理較少量的高品位礦石可降低磨礦、浮選和其他階段的加工成本。

減少環境足跡:及早丟棄大量廢石可減少整個作業的尾礦量、用水量和能耗。

提高項目經濟效益:更高的品位、更低的成本和更高的生產效率相結合,可以顯著提高項目經濟效益,包括提高內部收益率 (IRR) 和縮短投資回收期。

提高回收率:雖然並非所有黃金都能在分選步驟中回收,但分選出的礦石品位更高,從而提高項目的整體回收率。
