METHOD OF OXIDATION LEACHING OF NON-FERROUS METALS OUT OF SULPHITE MATERIALS

摘要

A method of pressure oxidation leaching of non-ferrous metals out of the sulphite materials by using oxidants is described. The sulphite materials are continually agitated with the oxidant at temperature ranging from 120 to 250 degrees Celsius. The solution is suitable for a hydro-metallurgic metal production, wherein a layer of solid reaction product is formed on the leached surface during the leaching process.
