PURIFICATION PHASES OF ZINC SULPHATE SOLUTION OBTAINED FROM NEUTRAL LEACHING PROCESS OF ZINC CALCINE
: The aim of this paper is based in analyze of the zinc sulphate solution obtained fromneutral leaching process of zinc calcine in "Trepca" and its purification from impurities. This solutionbesides zinc contains also and other impurities such as (Cu, Cd, Co, Ni, As, Ge, Sb, Se, Te, Ag etc.),which are with different concentrations. The sulphate solution can released from metal impurities basedon the fact that they have higher electro - chemical potential than zinc and, as such, during the refiningprocess they separate and precipitate in metallic form. Treatment of solution with appropriatetechnological methods technologically is very important in continuation of the electrolysis process and isaccompanied by economic effects, because of non-ferrous and rare metals benefit. In this paper aredescribed the phases of the purification process including acidic purification, cooling, needed materialsand equipments for the refining process. Also, special attention is dedicated to the factors that haveinfluence in the process development such as concentration, temperature, time, compressed air, etc.
