The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What's leftover is called tailings. Ballarat Gold Mine uses its robust management and monitoring processes to make sure its produced gold tailings comply with all license conditions and permits necessary for the safe storage of tailings.

This increases the production of gold without increasing the amount of ore mined. The underflow water ratio in the tailings thickener dropped from 0.85 tonnes water to 0.75 tonnes water per tonne of solids processed – an 11 per cent reduction in water going to the tailings dam (even with the higher tonnage).

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...
