Геохимические особенности и их роль в оценке и освоении пластово-инфильтрационных урановых месторождений Шу-Сарысуйской и Сырдарьинской провинций Казахстана

Abstract

The geochemistry of rocks and waters of productive horizons forms the redox environment of the subsoil and determines the main ore-controlling factor in the formation of «roll-front» uranium deposits in the Shu-Sarysu and Syrdara provinces. Increasing the consumption of leaching agents because of the high electrochemical activity of harmful impurities as well as colmatation effects create technological obstacles to the development of deposits by the sulfuric acid method of in-situ leaching, and therefore several blocks belonging to the technological imbalance (mainly in terms of carbonate content, CO2 >= 2 %).
