AUSTRALIA – The start-up of the gravity circuit at the BALLARAT GOLDFIELDS mine in the Victoria province is reported by the manufacturer, GEKKO SYSTEMS. The project is located in the prolific Ballarat Gold Province, which has a production history going back 150 years.
Ballarat’s new project includes an underground mine and gold recovery plant. The plant has nominal capacity of 600,000 tonnes of ore per year. The design incorporates two-stage crushing, an ore storage bin, and tertiary crushing. The final size reduction, to 80% passing 650 microns, is made in six vertical shaft impactors. The Gekko gravity system runs in closed circuit with the impactors. It consists of rougher and scavenger in-line pressure jigs plus a cleaner jig. A falcon concentrator is used to scavenge the final tail. Future expansion of the gold plant will include a cyanidation circuit.
