<p>A method for recovery of both sulfur and metal values from sulfide ores comprising adding a non-sulfide metal containing material to balance the sulfide-recoverable metal mole ration in the ore to at least 1:1 while leaching the metal sulfides at a pH of at least 7 and recovering all sulfur and metal values from the leach solutions. The process provides for all sulfur recovery as sulfuric acid and is nonpolluting, uses no neutralizing agents, and produces no waste products.</p> |
