A deteriorating quality of concentrates, together with secondary raw materials involved in the processing, causes lead and arsenic to circulate in semi products of copper smelting production, often accumulating in dust. Returning the dust into pyrometallurgical processing will lead to contamination of blister copper by arsenic and lead. Based on laboratory results, a technology for complex processing of thin dry electrostatic dust from Zhezkazgan copper plant was offered. The technology includes leaching by employment of sulfuric acid with a 300 g/l concentration, and addition of 0.1% of the original dust’s weight at the temperature of 90 °C, L:S = 5:1 (duration is 180 minutes). The degree of extraction of main components in the solution is 78.2% of Cu; 86.3% of Zn; 71.6% of Cd; 97.2% of Re; 95.3% of As. During the initial stage, copper and arsenic are separated from the sulfate solution with the help of electrolytic decoppering. In the second stage, rhenium is extracted with a sorption technique that uses a carbon sorbent from Kazakhstan raw materials. In the third stage, sorbate is processed by cementation to produce a copper-cadmium sponge. After that, the cementation solution is sent for separation of zinc production, whilst the copper-arsenic sludge gets processed with the method of hydrochemical sulphidation in a vitriol solution with addition of elemental sulfur in order to produce copper sulfides and arsenous acid. This stage of the technological scheme enables a selective extraction of copper and arsenic in the form of sulfides. The copper sulfides are sent to pyrometallurgical processing of copper production. Arsenic sulfides can be stored as a substance with a minimum (III–IV) hazard category.
This work was carried out within the project FPTs14 (ПЦФ14).
