Recovery of zinc from cyanide tailings by ,

However, due to the depression of cyanide, the other minerals, containing metals such as zinc, lead and copper, are difficult to recycle from cyanide tailings So the elimination of depressant remaining from initial processing or surface species formed during initial processing which will cause further depression on re-processing is critical for the recovery of these valuable minerals...
