Catalytic Oxidation Pretreatment of Sulfide-Rich Arsenic-Bearing Refractory Gold Concentrate by Hydrogen Peroxide in Sulfuric Acid in Tongling, China

Abstract:

This paper summarizes the result of experiment that was fourced on investigation of oxidation pretreatment on sulfide mineral for leaching of refractory gold concentrate by hydrogen peroxide in sulfuric acid. For a viable option, extraction rate of Fe, Cu was low, but extraction rate of arsenic reached nearly 100%. As the result of oxidation, elemental sulfur was not produced.
