Bioleaching: Introduction, Methods, Application, Copper, Microorganisms, and Processes! Introduction to Bioleaching: Leaching process was first observed in pumps and pipelines installed in mine pits containing acid water. This process was later on employed for recovering metals from ores containing low quantity of the metal. Presently certain metals from sulfide ores and other ores are

Bioleaching an overview ScienceDirect Topics

Little difference in the bioleaching efficiency between one-step and two-step methods was observed in the case of the spent NiMo/Al 2 O 3 catalyst. Thus, for the spent catalyst as received, the extractions of Al, Ni, and Mo were similar, as it is shown in Fig. 11.11 [650].However, for smaller particles (e.g., 100–150 μm and <37 μm), the dissolution of Ni and Mo was higher than that of Al.

Methods of Metal Recovery by Microorganisms (2 Methods)

Bioleaching is the method of choice for the large-scale production uranium from its ores. Uranium bioleaching is widely used in India, USA, Canada and several other countries. It is possible to recover uranium from low grade ores (0.01 to 0.5% uranium) and low grade nuclear wastes. In situ bioleaching technique is commonly used for extracting
