Application Of Bioleaching To Copper Mining In Chile

Early application of bioleaching to copper mining centred in its recovery from dumps (Gentina and Acevedo 1985 Acevedo 2002) This is a low technology process and renders low productivities and recoveries Nevertheless dump bioleaching is economical mainly because it recovers copper.Copper production from the process increasing from 0 2 to approximately 8 10 Bioleaching of copper in heaps was first recorded at the Rio Tinto mine in 17th century The first modern industrial scale copper heap bioleach producing 14 000tpa commenced in 1980 at Lo Aguirre in Chile.
