Biological Oxidation is the latest technology that ensures better processing of gold ores with high Sulphur content. Ores at Cam and Motor gold mine have high Sulphur concentration increasing cyanide consumption during the leaching process.

The technology uses bacteria to reduce Sulphur content before cyanidation. The mine is reported to have received 20 litres of bacteria from neighbouring South Africa and has developed enough to feed the three tanks. This innovative solution for the treatment of ores significantly reduces cyanide consumption, therefore reducing operating costs.

The BIOX plant is one of the key projects expected to get the firm’s turnaround strategy back on track. According to RioZim’s abridged press circular, recent geological and metallurgic test work revealed that with the current technology and the grades of ore, Cam and Motor can produce significant amounts of gold at a competitive cost of production.
