Gold Processing at Boddington Mine

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 m.
