The invention discloses a processing method for removing miscellaneous residues in sulfide. The processing method comprises the steps: drying materials until a moisture content is lower than 1%, thenbreaking and sieving, restoring the sieved material in hydrogen atmosphere, guiding restored gas out by an induced draft fan, utilizing sodium hydroxide to absorb the restored gas, leaching metal powder by ammonium and carbonate, separating cobalt, nickel and copper from other metal, separating zinc and manganese from cadmium and lead through metal activity difference, then extracting and oxidizing to separate copper, cobalt and nickel, achieving zinc and magnesium separation through oxidization and utilizing sulfuric acid leaching to achieve lead and cadmium separation. The processing methoddisclosed by the invention has the advantages of short flow and simple technology; furthermore, all components can be separated and recycled, and the yield is high; in addition, a final obtained product has the advantages of high purity and large product added value; sulfur ions can be recycled and cyclically utilized, and effects on environment are small.
