PROCESS FOR RECOVERING METALS BY REDUCTION AND CARBONYLATION

摘要

A process for treating a feed material composition includes a solid particulate precious metal material-rich feed material composition fraction and a solid particulate rare earth metal material-rich feed material composition fraction, in which the solid particulate precious metal material-rich feed material composition fraction includes one or more precious metals, and in which the solid particulate rare earth metal material-rich feed material composition fraction includes one or more rare earth metals. The process includes contacting the solid particulate feed material composition with a reducing agent within a reducing agent contacting zone to effect production of a reaction intermediate solid particulate material composition.
