Research of copper recovery from oxidized and poor ores of Aktogay mine using heap and bacterial leaching and subsequent implementation of the heap bioleaching project at the Aktogay mine

This article discusses different types of leaching and a complex of works on research and the implementation of bioleaching technology at the Aktogay mine to increase copper recovery from oxidized copper ores. Bacterial leaching (Bioleaching) is a hydrometallurgical process of extracting chemical elements or their compounds from ores, concentrates, technogenic raw materials with the help of microorganisms1.
