  Our research supports the necessary transformation of the materials extraction and recycling processes in order to mitigate their environmental impact and accommodate a global market dominated by China. We develop processes that target higher productivity, lower GHG emissions and limited water and chemical consumptions. The developments reported herein are applicable to primary extraction, anchored in the reality of mining challenges such as liberation size or low ore grades (for example nickel or copper). Our findings extend to recycling and downstream recovery, in particular for products containing rare-earths, precious metals or even cobalt. Our processes enable to upgrade, with minimal cost and environmental impact, mixed solid compounds such as crushed ores, slags, tailings or recycled streams. We efficiently transform such feeds into new solid phases that are amenable to cost effective and well established recovery with physical separations technologies. Furthermore, we have demonstrated the unique ability to use those stream to recover metallic products with more cost efficient technologies that are integrated with the deployment of green electrical power.
