Обоснование основных параметров гидрометаллургической переработки руд зоны «Антимонитовая» месторождения «Дельмачик»

The article puts a spotlight on processing of gold ore from Antimonite Zone of Delmachik deposit. The ore contains the associate minerals of antimony, arsenic and sulfur. The results of the laboratory-scale hydrometallurgical testing of different ore sizes in direction cyanation and post-cyanation sorption of different duration; post-cyanation sorption after preliminary atmospheric oxidation; cyanation with varied concentrations of cyanide and lime consumption, solution pH and duration are presented. The oxidized gold ore leaching products were analyzed using modern physicochemical methods such as the spectrochemical analysis, IR spectroscopy, scanning electron microscopy, X-ray phase analysis and percolation leaching. These techniques made it possible to examine the chemistry and mineral composition of the initial ore and processing products, as well as to determine regime parameters for processing at maximum recovery of valuable components. The dynamics of leaching and reagent flow rate is studied, and the dependences of gold recovery on the process duration are obtained. Optimization of gold leaching from ore at the laboratory and semi-industrial scale enables creation of an efficient hydrometallurgical processing technology.

Keywords: gold ore, hydrometallurgical processing, parameters, heap leaching, gold recovery, solution, sorption mode, process parameters.
