Biooxidation process for recovery of metal values from sulfur-containing ore materials |
摘要 |
A hydrometallurgical process for the recovery of one or more metal values from a metal ore material in the presence of clays and/or fines material said ore material being comprised of one or more metal values and a matrix material having a sulfur content wherein the sulfur is present in an oxidation-reduction state of zero or less. The process comprises forming particulates from particles of said ore material, particles comprising said clays and/or fines material, an acid-resistant polymeric agglomeration aid and an inoculate comprising bacteria capable of at least partially oxidizing the sulfur content; forming a heap of said particulates; biooxidizing the sulfur content and recovering those one or more metal values.
