Elevated temperatures favor bioleaching processes through faster kinetics, more favorable
mineral chemistry, lower cooling requirements, and less surface passivation. Extremely …

Jarosite, beudantite and alunite are members of the alunite supergroup. Minerals like those
have been detected in different environments on Earth. These jarosite-type compounds are …

The growing worldwide demand for copper implies the need to process increased amounts
of its ores. Chalcopyrite is the most abundant copper mineral, but due to its refractory nature …

Chalcopyrite is the most abundant Cu-sulfide and economically the most important copper
mineral in the world. It is known to be recalcitrant in hydrometallurgical processing and …

The world is witnessing a major challenge of energy transition which involves the decline of
fossil fuels specifically, but which increasingly calls on metallic resources, base metals …

In this study, bacterial leaching of zinc, copper and antimony from tetrahedrite concentrate
was investigated with mixed mesophilic and mixed moderately thermophilic …

Many acidophilic iron-oxidizing bacteria used in the mining industry for the bioleaching of
sulfidic minerals are intolerant to high chloride concentrations, resulting in problems where …

Chalcopyrite is the most abundant copper mineral and its bioleaching has been the subject
of several studies due to its refractory nature when submitted to hydrometallurgical …

This study aimed to assess the influence of the physical-chemical factors (particle size,
shake flask speed, starting pH, and pulp density) in bioleaching of Zambian chalcopyrite …

Medical waste (MW) is originated from healthcare activities, which is difficult to dispose and
potential to cause environmental pollution. The effect of MW on bioleaching of low-grade …
