Highland Copper Enhances Recovery with Latest Metallurgical Work
Highland Copper Company Inc. (TSXV: HI; OTCQB: HDRSF) is making headlines with its recent advancements in metallurgical testing for the Copperwood Project. This promising news emerges from their ongoing commitment to optimize the processing techniques at their site in Michigan, showcasing not only a significant increase in copper recoveries but also a decrease in processing costs.
Metallurgical Testing Program Overview
In pursuit of elevating their technological framework, Highland Copper kickstarted a metallurgical test program aimed explicitly at refining their process plant design. By integrating ultrafine flotation technology alongside new operational cost structures, their team has managed to revamp the existing plant’s circuit to enhance performance. One of the highlights of this initiative includes achieving a remarkable copper recovery rate elevated to an impressive 87.6%, all while trimming down both capital and operational expenses.
Redesigned Processing Plant Setup
The redesigned process plant reflects a more efficient comminution circuit paired with an effective flotation circuit that employs Jameson cell technology. This configuration not only optimizes the overall design but also ensures reduced power consumption, showcasing Highland’s commitment to enhancing energy efficiency. With Glencore Technologies stepping in to provide performance guarantees, the company is now poised to forge ahead confidently with the metallurgical advancements.
Significance of Phase 1 Engineering
The ongoing Phase 1 in detailed engineering, initiated alongside the test program, marks a crucial step for Highland Copper. It encompasses essential design criteria that pertain to the process plant, tailings management, and water usage. Dr. Wynand van Dyk leads this project, contributing his extensive expertise in Chemical Engineering and Extractive Metallurgy gathered over a prolific 30-year career.
Key Highlights from Metallurgical Tests
Among the numerous tests conducted, the following standout results further underscore Highland’s progress:
- Comprehensive Testing Program: A total of 45 kinetic rougher and cleaner flotation tests refined the grind parameters while also experimenting with pilot-scale ultrafine flotation technology.
- Optimized Process Circuit: The implementation of a mill-float-mill-float (MF2) configuration incorporates a de-sliming stage, thereby allowing for a mass rejection of 25% from primary flotation tailings and achieving substantial operational savings of energy.
- Enhanced Reagent Scheme: Through the new reagent suite, Highland estimates potential savings of up to $1.00 per tonne milled, further elevating their environmental performance.
Next Steps and Future Prospects
Highland Copper is gearing up for the next phase by completing lock-cycle variability testing, which is expected to conclude soon. Following this, final design criteria will be confirmed, setting the stage for the next round of engineering advancements. The company is keen on progressing to a construction decision, projected for 2026, providing both stakeholders and investors with a clear pathway forward.
