Recovery of metals from sulfur bearing ores |
| abstract |
Sulfur monochloride is reacted with an ore containing iron, sulfur and a metal which forms a water soluble ammine complex or an ammonium-containing double salt, to yield metal chlorides and sulfur. The metal sought is solubilized with an aqueous solution containing ammonium ions to produce an aqueous solution of metal ammine complex or double salt and thereby separate such complex or salt from the iron and sulfur. The solution containing the sought metal values can then be subjected to electrowinning to recover the metal, or the metal can be precipitated as the metal oxide by the addition of sodium hydroxide. Sulfur and chlorine are recovered during the process and used to regenerate sulfur monochloride. |
