Gold Processing at Boddington Mine

Gold processing plant at Boddington mine

The Boddington Gold Mine is a gold and copper mine the largest gold mine in the country, located about 130km south-east of Perth in Western Australia and 17 km northwest of Boddington

The Boddington deposits were previously mined between 1987-2001 for the production of 6.1 Moz of gold. The current mining operation is of significantly larger scale, producing 696 000 ounces of gold in 2014, along with 69 million pounds of copper.

Built on the footprint of the original Boddington gold mine, the operation involves open cut mining from two large pits. The process flow sheet at Newmont Boddington Gold (NBG) comprises primary crushing, closed circuit secondary and tertiary crushing using High Pressure Grinding Rolls (HPGR), ball milling and hydro-cyclone classification to generate a milled product with a P80 of 150 ┬Ám. The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.
