Tank leaching BioMineWiki Skellefteå

Bioleaching tanks have capacities of up to 1300 m 3). Therefore the main operation costs are for mixing and air-supply, but also cooling of the reactor and neutralisation of the bioleach liquid are major costs in stirred tank bioleaching. In many of the recently started refractory gold treatment plants, bioleaching is the preferred technology.

Gold Leaching Agitation Tanks

The mixing of solids suspended in a fluid medium is still largely an art. The development of fundamental laws governing the operation is complicated by the large number of variables involved, some of which can hardly be evaluated in mathematical terms. Practical studies of the circulation patterns of the more common types of agitators are to be found in chemical engineering literature. In one

Producing Copper Nature's Way: Bioleaching

Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
