Selective Separation Recovery of Copper and Arsenic from the Leaching Solution of Copper Soot

Through the main chemical reaction of metal ions and S2−, a new type sulfide precipitant was first prepared used to realize selective separation recovery copper arsenic from leaching solution soot. It is proven by experimental results that could efficient arsenic. Indeed, slag with Cu grade about 47% trisulfide As operation 98% be obtained. The energy calculation analysis SEM images illustrate mainly depended on reactions precipitation. S2− HS− produced react Cu2+ components form CuS As2S, respectively, in procedure. In addition, smaller solubility lower rate engendered were key achieving
