The current mining operation is of significantly larger scale, producing 696 000 ounces of gold in 2014, along with 69 million pounds of copper. The process flow sheet at Newmont Boddington Gold (NBG) comprises primary crushing, closed circuit secondary and tertiary crushing using High Pressure Grinding Rolls (HPGR),.
These superstructures are flow networks between several separation stages. In each separation stage two kinds of cells are allowed, bank and column. In several streams in the CPS and TPS, the incorporation of regrind mills is also included. The optimal selection of the circuit is made with an appropriate objective function,.

Parallel grinding circuits using dual geared drive systems selected due to: • higher installed SAG mill power (available with geared mills) achieved required maximum.
The secondary mill product was then floated in the secondary rougher flotation. Further regrinding of primary and secondary rougher concentrate to 15 and 10 μηι, respectively was required to liberate copper-bearing minerals to achieve the desired copper concentrate grade. This circuit, known as the 'Frozen Flowsheet',.

The figure above is a simplified flow sheet showing the basic steps involved in a copper mill producing the byproduct molybdenum. The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for.
A multi-stage flotation circuit using an arrangement of mechanical cells, regrind mills, and column cells produces copper concentrate. Final flotation copper concentrate with gold and silver by-product metals is thickened, filtered, and stored on site. The PAC concentrator flowsheet comprises a closed-circuit crushing plant.
