The reserves of most high-grade ores are finite, and their future availability is critical. It is becoming of increasing importance and economic interest to be able to extract these metals from low-grade ores and secondary sources using tailored, bespoke processing routes – often representing combinations of mechanical, pyro-, and hydrometallurgical processes.

SMS group Process Technologies in Vienna/Austria develops advanced processes and plants for the extractive metallurgy of technology and battery metals, for the production of battery-grade chemicals and pigments, and for the recycling of waste batteries and WEEE. New processes and flow sheets are tested and verified in the company’s own laboratory and piloting facilities.
