BGR - Metal Bioleaching (Biomining)

In industrial bioleaching (biomining) three technical processes are differentiated: Heap or dump bioleaching, tank bioleaching, in situ or in place bioleaching. Today the recovery of copper from sulfide ores is the most important industrial application, and a significant proportion of the world copper production originates from heap or dump bioleaching. Furthermore biomining is applied for the

Bioleaching - Wikipedia

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt

Bioleaching - an overview | ScienceDirect Topics

Bioleaching can be defined as a hydrometallurgical dissolution process promoted by microorganisms for the recovery of metals from their ores/concentrates. The bacterial oxidation of sulfide minerals permits biodissolution of metal ions of interest such as zinc from sphalerite and, copper from chalcopyrite, covellite, and chalcocite.

The process can be used on ores that are only 0.5 to one percent copper, too little for conventional refining. The solution is then drained in to an electrolytic cell and copper extracted from it. In addition, studies show that zinc, nickel and cobalt can also largely be extracted by the process of bioleaching (Rawlings, Douglas, and Johnson 2007).
