Summarizes information on the latest biotechnology methods of leaching ferrous, rare and precious metals from raw mineral and secondary technogenic materials and systematized data on the suitability of carboxylic acids to leach metals from mineral component. The mechanisms of interaction of carboxylic acids with mineral raw materials of different origin; defined physico-chemical (thermodynamic and kinetic) parameters and processes of organochemical and microbial leaching. The key factors - the composition of ores, degree of dispersion, acidity, leaching temperature, mixing ratio of liquid and solid phases and other factors, fundamental for the effective dissolution of minerals. A principal flowsheet of complex technology of organochemical leaching ferrous, rare and precious metals from mineral raw materials was done Product Description popup.authors Алексеєв О.Ф.
