Role of chemistry and microbiology in mining: current situation and long-run objectives

The article offers an overall estimate of efficiency of chemical and microbiological methods in mining technologies at the current stage. The presented data prove a positive trend in the advanced technologies of mineral mining in the countries with the developed mining industry, including the physicochemical geotechnology (in-situ, borehole and heap leaching). The role of chemistry and microbiology as basic sciences in the advancement of physicochemical extraction of metallic and nonmetallic minerals from natural and manmade deposits is demonstrated. The challenges of the mineral mining sector in Russia in the early 21st century are discussed. The current problems connected with extraction of valuable components from mineral raw materials are analyzed. The key objectives are formulated for the theoreticians and practitioners in mining in order to enhance the technological efficiency, to reduce the cost of mineral mining, to shorten the time of new field development, to save capital and operational expenses and to simplify technologies of metallic and nonmetallic mineral extraction. The main routes of advancing the mining art based on the scientific achievements are identified. The prospects of the chemical and microbiological methods in mining are studied.

Keywords: physicochemical geotechnology, in-situ leaching, borehole leaching, heap leaching, available advanced technologies, chemistry, microbiology, chemical and ecological problems.
