MINING ELECTRONIC WASTE A NEW LIFE FOR USED METALS “Our processes are based on complex lead/copper/nickel metallurgy, using these base metals as collectors for precious metals and other metals, so called "impurities", such as antimony, bismuth, tin, selenium, tellurium and indium.” —Umicore
“E-scrap, including LIB-scrap, is placed in a copper smelting converter after pretreatment. After that, it is separated into crude nickel sulfate by electrolysis and sent to a nickel refinery to become pure nickel sulfate, which is used as a raw material for batteries.” —Sumitomo Metal Mining
“Thanks to the modular structure of our new recycling systems, we are able to react very flexibly to the market and needs and thus return more and more metalcontaining materials to the material cycle.” —Aurubis
