| 简介 |
There is provided a process for treating a feed material composition including a solid particulate precious metal material-rich feed material composition fraction and a solid particulate rare earth metal material-rich feed material composition fraction, wherein the solid particulate precious metal material-rich feed material composition fraction includes one or more precious metals, and wherein 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. The reaction intermediate solid particulate material composition is contacted with carbon monoxide within a carbonylation zone so as to effect production of a solid particulate post-carbonylation material composition. |
