PROCESS FOR RECOVERING METALS AND METAL COMPOUNDS FROM MINED ORE AND OTHER METAL-BEARING RAW SOURCE MATERIALS |
摘要 |
A method for selectively recovering a metal from mined ore and other metal-bearing raw source materials is disclosed. The method involves mixing with an aqueous medium a metal-bearing ore and/or other raw source material containing a first metal in an insoluble form, insoluble and/or soluble Cr in a Cr bearing material as a second metal, and organic and inorganic compounds to obtain a slurry containing the first metal in an insoluble form, insoluble and/or soluble Cr compound(s), and the organic and inorganic compounds; adjusting the pH of the slurry to an optimal range for Cr oxidation to convert Cr to an insoluble form; optionally adding a first oxidizer to the slurry to oxidize organic and inorganic compounds; selectively leaching the Cr by adding a leaching agent in an amount sufficient to obtain Cr in a soluble form while the first metal remains in the slurry in an insoluble form; filtering the slurry to obtain a filter cake containing the first metal in an insoluble form and a filtrate containing Cr in a soluble form; and recovering the filter cake containing the first metal in an insoluble form and/or filtrate containing Cr in a soluble form. |
