Abstract
An assessment of the existing methods of controlling the quality of mineral raw materials during mining and possible ways of increasing their efficiency is presented. Criteria for evaluating the ore massif are given, depending on the mineral and chemical composition, structural and other features. As a result of the studies, the problem of increasing the efficiency of ore preparation was solved based on the use of chemical analysis of the granulometric composition of the processed ore (charge), which provided an increase in the extraction of the useful component, which makes the model of the charge of ores from various deposits more accurate.
Highlights
Technological schemes for the processing of gold-bearing ores, depending on the characteristics of the mineral, phase, chemical, granulometric composition, the size and geometric shape of gold particles, the purity of the surface of gold grains, which determine the "obstinateness" of raw materials, are very diverse and include dozens of technological operations that combine enrichment, and chemical and metallurgical processes

Ore preparation is a set of ore processing activities made by various methods to obtain particle size and material compositions determined by the requirements of subsequent processing or standards for finished products
Summary
Technological schemes for the processing of gold-bearing ores, depending on the characteristics of the mineral, phase, chemical, granulometric composition, the size and geometric shape of gold particles, the purity of the surface of gold grains, which determine the "obstinateness" of raw materials, are very diverse and include dozens of technological operations that combine enrichment, and chemical and metallurgical processes. The parameters of the material composition are determined during technological sampling, geological and technological modeling, which are carried out at all stages of geological work, technological assessment and industrial processing of ores [1,2,3]
