Wiluna Gold Mine - BIOX Process

BIOX Process

The BIOX process is a pretreatment process for refractory gold ores or concentrates, using naturally occurring bacteria to break down the sulphide ore and liberate the gold for subsequent cyanidation. The advantage of the BIOX process is its environmental friendliness. BIOX was first commercially used in 1988 and the Wiluna plant was installed in 1993.
