As near-surface oxide orebodies are depleted, mines are having to process deeper sulfide ores that are lower in metal grade and metallurgically more complex. Modern technologies that are simple, cost effective and environmentally sound are required for their extraction. In many cases, bioleaching is the most suitable process.

A 100 tonne per day Bacox™ plant was commissioned in 2001 at the Shandong Tiancheng Biotechnology Gold Industry facility (formerly the Shandong Tarzan BioGold facility) near Laizhou in PR China. A high gold extraction (over 95 per cent) is achieved on cyanide leaching of the oxidised residue.
