Biomining: metal recovery from ores with microorganisms

Bioleaching is a conversion of an insoluble valuable metal into a soluble form by means of microorganisms. In biooxidation, on the other hand, gold is predominantly unlocked from refractory ores in large-scale stirred-tank biooxidation arrangements for further processing steps. In addition to copper and gold production, biomining is also used

gold processing

gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less

29.10.2014The Abitibi Belt, Canada. The Archean Superior Province of Canada contains the Abitibi greenstone belt, which contains some of the world's largest gold and copper-zinc deposits with significant amounts of nickel-copper-platinum group element (PGE) mineralization too. Discovered in 1909, the Abitibi has generated over 160 million ounces of gold.

The selective leaching of copper from a gold–copper concentrate

system to leach gold over copper from oxidised ores has been tested successfully using different gold–copper ores (Drok and Ritchie, 1997; La Brooy et al., 1991; Muir et al., 1989). However, this system in the treatment of transition or sulphidic ores gave poor gold recovery and required higher reagent concentrations (Muir, 2011). Moreover, both

Increasing the recoverability of gold from carbonaceous gold

The recoverability by cyanidation of the gold content of sedimentary gold-bearing ores containing organic carbonaceous material and gold-bearing pyrite, or other gold-bearing sulfides, is greatly increased by heating an aqueous slurry of the ore to about 167.degree. to 212.degree. F. and then introducing air or oxygen into the heated slurry to oxidize and
