Process for the Separation and Recovery of metal Sulphide ore or Concentrate Mixed Sulphide

摘要

It provides a process for the separation of at least one Metallic sulfide from a mixed sulfide Concentrate.The process can include: Put the Mixed Flotation of Sulphide Concentrate is subjected to Flotation where at least one comprising antimony sulfide,A First Metal and Arsenic and sulfur is depressed at least comprises a Second metal.Floating provides a First metal Concentrate with the at least one comprising antimony sulfide,Arsenic and the first Metal and a Second metal Concentrate with the at least one comprising the second metal sulfide.The First metal Concentrate is leached to give a Concentrated and a Leach Solution.The Concentrate further comprises the first Metal and the Leach Solution includes soluble soluble Arsenic and antimony.The process can also include the oxidation Leach solution to give a precipitate of a solution of antimony and ArsenicAnd form a stable Compound of arsenic from Arsenic Solution.
