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.Copper Bioleaching in Chile - mdpi,Chile had the first commercial operation in the world exclusively via bioleaching copper sulfides. Nowadays, all bioleaching operations run in the country contribute to an estimated 10% of total copper production. This article presents antecedents that have contributed to the development of copper bioleaching in Chile.Recsk mine - Wikipedia,The Recsk mine is a large copper mine located in the north-east of Hungary in Heves County.Recsk represents one of the largest copper reserve in Hungary and in the world having estimated reserves of 770 million tonnes of ore grading 0.65% copper..

Recsk Mine (Deep Level), Recsk, Mátra Mts, Heves Co., Hungary : A copper mine located NE of Budapest.Study on Selective Depression of Pyrite during Copper,,During chalcocite and pyrite bioleaching, redox potential is important factor to influence of bioleaching rate and the results showed that pyrite and chalcocite bioleaching rate was correlated with redox potential. It is indicated that copper can be selectively bioleached during copper bioleaching by controlling redox potential of bioleaching.Bioleaching | Copper | Mining,Bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached.
