Removal of impurities from copper electrolyte with

2003-4-1  From Fig. 5, it can be found that given a certain amount of AB, the more the addition is, the less the total weight of removed impurities will be.In order to make full use of AB in the purification of copper electrolyte, the adsorption was conducted in the filter directly as well. The operation lasted for 4 h and 32 m 3 electrolyte was treated with about 400 kg AB.

Removal of Metallic Impurities from Off-Grade Copper

The removal of metallic impurities from off-grade copper concentrate was investigated in alkaline solution with H2O2. The analysis results of XRD and SEM-EDS revealed the oxidative mechanisms of all sulfides. The influence of various parameters of alkaline leaching were investigated including concentrations of sodium hydroxide and hydrogen peroxide, liquid to solid ratio, leaching time and

Thermodynamics of removing impurities during copper

2018-6-16  The removal of impurities from matte and from copper during copper smelting is discussed thermodynamically. Two mechanisms are considered: oxidation followed by slagging; and volatilization. In matte, most of the undesirable impurities such as lead, antimony, bismuth and arsenic are not removed by oxidation, but rather by volatilization.
