Vale Base Metals Celebrates Innovation in Circular Mining
Vale Base Metals has unveiled the winners of an innovative competition designed to boost the recovery of valuable metals from pyrrhotite. This challenge, called the Pyrrhotite Resource Recovery Innovation Challenge, aimed to encourage researchers, innovators, and entrepreneurs to present cutting-edge solutions for processing low-grade pyrrhotite tailings. These tailings are the residual materials left from the processing of sulphide ores.
After a thorough selection process, three exceptional solutions were recognized as laureates, and each received a prize of C$25,000 for their remarkable contributions. Adam McMillan, the Director of Research and Innovation at Vale Base Metals, expressed excitement about these outcomes. He stated, "We are thrilled to recognize these innovative solutions that not only unlock value from waste but also contribute to sustainable mining practices. The ingenuity and dedication demonstrated by the laureates are truly inspiring, and we look forward to seeing the impact of their work on the future of mining."
Meet the Innovative Laureates
Let's take a closer look at the three laureates whose ideas stood out in this competition.
Columbia University
Dr. Behzad Vaziri and his team from Columbia University proposed a unique method to recover value from pyrrhotite tailings. Their process not only generates elemental sulphur and iron but also creates a non-corrosive sulfate solution that operates without the need for a pressure vessel, showcasing both sustainability and efficiency.
Innord Inc
Another remarkable solution came from Daniela Rossetto and her team at Innord Inc. They developed a sustainable approach for valorizing pyrrhotite tailings, yielding high-grade iron oxide, elemental sulphur, and nickel concentrate, which can be processed through conventional methods. This approach could significantly enhance the value of these low-grade tailings.
Canadian Mineral Technology Inc
Peter Kondos and his team at Canadian Mineral Technology Inc introduced the PRO chloride process, which transforms pyrrhotite tailings into valuable products using chloride hydrometallurgy. This innovative technique promises potential benefits in mining and materials recovery.
