    Oct 22, 2011· Biomining is slower than traditional mining techniques and is not applicable to a wide variety of ores. Biomining has disadvantages such as the lack of complete control over the conditions of biomining, leading to unpredictable or inefficient extraction rates. Production of acid (sulfuric acid) is a major problem associated with bioleaching.

    Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from lowgrade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

    Biomining entails the use of acidophilic microbes to facilitate the recovery process of metals from sulfide minerals in the processes of bioleaching and biooxidation. Biooxidation is the enrichment of metals, particularly gold, by mobilization and thus removal of interfering metal sulfides from ores bearing the precious metals ( Rohwerder et al., 2003 ).
