Extremely thermoacidophilic archaea for metal bioleaching: What do their genomes tell Us?
Bioresource Technology, 2023 Elevated temperatures favor bioleaching processes through faster kinetics, more favorable mineral chemistry, lower cooling requirements, and less surface passivation.

Two-Stage Oxidative Leaching of Low-Grade Copper–Zinc Sulfide Concentrate
Microorganisms, 2022 Bioleaching may be effectively used to extract nonferrous metals from sulfide ores and concentrates. At the same time, some minerals are refractory and their bioleaching rate is often comparatively low that does not allow the required metal extraction ...

Effects of Fe3+ and Ag+ on Column Bioleaching of a Low-grade Sulfide Copper Ore
International Journal of Electrochemical Science, 2019 Due to the consumption of high-grade ores and the increasing demand for copper, the utilization of low- grade copper-bearing ores has become a prominent area of research. In this study, column bioleaching was adopted to separate low-grade copper ore. The
