PROCESS FOR RECOVERING METALS FROM SILICATE MATERIALS

摘要

There is provided a process for treating a silicate material. The process includes contacting operative metal material-comprising silicate material with a reagent mixture so as to effect production of a pre-carbonylation operative metal material-comprising material, wherein the operative metal material-comprising silicate material includes operative metal material to thereby define a silicate material-based operative metal material fraction, and wherein the pre-carbonylation operative metal material-comprising material includes a pre- carbonylation material-based operative metal material fraction that includes at least a fraction of the silicate material-based operative metal material. At least a fraction of the pre-carbonylation material-based operative metal material is then carbonylated. The operative metal material is defined by at least one operative metallic element, the operative metallic elements being defined by nickel, iron, and cobalt. The reagent mixture includes at least one halide-ion donating agent and at least one reducing agent.
