The electrochemical technology of gold extraction from sulfide ores

The article is aimed at identifying patterns of behavior of minerals under the influence of the influence exerted on them. The results of an experiment on the tailings of gold ore enrichment are presented. Metal extraction processes are improved by increasing the activity of reacting substances. Deep processing of ore processing waste is carried out by radically changing their properties at the molecular level. Among the methods of activating ore processing processes, the method of electrochemical gold extraction is promising. The study of the effectiveness of the electrochemical method includes experiment, systematization of variable factors, regression analysis of indicators, graphical interpretation and engineering forecasting. The criterion for the effectiveness of combining enrichment methods is to increase the extraction of metals. According to the results of the study of the behavior of sulfides, the redox potential of the reagents was ranked, the factors influencing the process and the proportion of gold extraction depending on them were determined, graphs of the dependence of metal extraction were constructed and the nature of the dependence of overvoltage on current density was established differentially for electrolyzers: with a diaphragm or membrane. It is proved that electrochemical chlorine oxidation of ores in suspension and pulp accelerates the process of decomposition of minerals and provides a comprehensive ecological and economic effect, and the obtained patterns of gold production are universal. The relevance of the study is due to the need to involve in the production of stocks of substandard for traditional enrichment of persistent sulfide ores. The materials of the article are of practical value for mining enterprises, first of all, mining gold, and then for mining other metals.
