milling and flotation process at fairview biox plant

BIOX Operations

The Fairview plant was the first commercial BIOX ® plant, and played a vital role in the ongoing development of the process. In 1984 a pilot plant was commissioned to treat flotation concentrate from Fairview. This plant operated for two years and its success led to the installation of a demonstration plant at Fairview.

Bacterial oxidation - Wikipedia

Bacteria biooxidation is an oxidation process caused by microbes where the valuable metal remains (but becomes enriched) in the solid phase. In this process, the metal remains in the solid phase and the liquid can be discarded. Bacterial oxidation is a biohydrometallurgical process developed for pre-cyanidation treatment of refractory gold ores or concentrates.
