Acid mine drainage (AMD) causes serious environmental pollution owing to its high acidity,
toxic metal content, and sulfate content. This review describes the mechanism of formation …

Heap leaching is a well-established extractive metallurgical technology enabling the
economical processing of various kinds of low-grade ores, which could not otherwise be …

This review outlines current research in heap bioleaching, particularly in respect of the
bioleaching of chalcopyrite, assesses the status of the bioprocessing of copper sulphides …

Compared to conventional extractive techniques, bacterial assisted leaching, also called
“biomining” is an eco-friendly technology that provides improved metal/solid separations …

The need to process low-grade and/or complex chalcopyrite-containing ores that cannot be
concentrated is the main driver for the development of hydrometallurgical processes. The …

Bioleaching offers a low-input method of extracting valuable metals from sulfide minerals,
which works by exploiting the sulfur and iron metabolisms of microorganisms to break down …

Solid metalliferous wastes (sludges, dusts, residues, slags, red mud and tailing wastes)
originating from ferrous and non-ferrous metallurgical industries are a serious environmental …

Leaching of chalcopyrite in sulphuric acid media has been investigated under constant
redox potential conditions in solution. The leaching residues were analysed by X-ray …
