The textbook contains information about the chemical and mineralogical characteristics of gold-containing ores of genetic and technological classification, technological properties of ores and minerals. Physico-chemical properties of noble metals and their mineral formations are considered. Characteristics of chemical stability and conditions of gold dissolution. The main methods of preparation of ores for enrichment . Features of the application of technological processes (ore processing, gravity, flotation, chemical-metallurgical and other methods) are noted . Gravitational-flotation technologies are considered. Hydrochemical processes of processing of ores, concentrates, leaching products in acids, solutions of cyanides, chlorine, iodine, bromine, thiocarbamide, thiosulfate . Examples of hydro- and nirometallurgical processing of gold-containing raw materials, including sorption-extraction and biochemical processes at Russian and foreign enterprises are considered. It is intended for students of the direction "Metallurgy" of the profile "Technology of mineral raw materials" of the specialty "Enrichment of minerals" and can be useful to specialists, researchers engaged in the processing of gold-containing raw materials .
