PURIFICATION PHASES OF ZINC SULPHATE SOLUTION OBTAINED FROM NEUTRAL LEACHING PROCESS OF ZINC CALCINE
Abstract
The aim of this paper is based in analyze of the
zinc sulphate solution obtained from neutral leaching process of zinc calcine
in "Trepca" and its purification from impurities. This solution
besides 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 based on the fact that they have
higher electro - chemical potential than zinc and, as such, during the refining
process they separate and precipitate in metallic form. Treatment of solution
with appropriate technological methods technologically is very important in
continuation of the electrolysis process and is accompanied by economic
effects, because of non-ferrous and rare metals benefit. In this paper are
described the phases of the purification process including acidic purification,
cooling, needed materials and equipments for the refining process. Also,
special attention is dedicated to the factors that have influence in the
process development such as concentration, temperature, time, compressed air,
etc.
