“…A biolixiviação em montes ("dump leaching") é baseada no mesmo mecanismo, porém utilizada em depósitos já existentes de rejeitos minerais próximos às minas, nos quais o teor do metal é baixo demais para o custo de sua recuperação [19].…”

“…The optimal conditions for the growth of microorganisms, such as aeration, humidity, pH, temperature, energy sources and nutrients, as well as the absence of potential inhibitors have to be ensured. 62 Selection of the suitable microorganisms for the leaching is one of the important factors. Various studies have shown that a mixed culture containing the iron and sulphur oxidizing bacteria is more effective than pure culture.…”

“…The literature and case study show (Gorman et al, 2004;Pradhan et al, 2008) that the variability of metallurgical recoveries through the ISL is associated with low or no control of geometallurgical variables such as fragmentation, aeration, and temperature. To overcome these deficiencies, the ISM method, in which leaching and conventional underground mining methods are integrated in a novel way, was proposed (Castro et al, 2013).…”

“…High dependence of the metallurgical recovery on the temperature was observed by Lorca (2004). The increase in the temperature reduces the passivation of the sulphide minerals and makes the passivation layer less stable (Lorca, 2004;Pradhan et al, 2008). The activity of leaching microorganisms also improves with increasing temperature (Kelly et al, 2008).…”
