Method for processing a Raw ore containing fe, s in the form of sulfide and to facilitate the Recovery of AG, AG comprising pressure oxidation,Recover a Liquid mixture of unloading and Leach, avoiding the formation of jarosite, through the use of a Binder material with sulfate carbonate type.

摘要

A method is described for the treatment of Sulphide Minerals containing Silver, by pressure oxidation,The Method comprises adding a material which binds with the sulfate to reduce the formation of jarosite species during the pressure oxidation.The Silver can be recovered from the solid portion of the mixture Liquid Discharge.Thus advantageously can be eliminated, the reduction step of jarosite, cooked through the Limestone, which is required to recover the Silver after the pressure oxidation.
