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 ...
