Ore processing operations at Newmont Boddington

Gravity was the first method developed to recover gold from ore to a variety of flowsheets from heap leaching to agitated leaching circuits Ores in which gold is locked with sulfides are processed by combining flotation with other methods All of these processes bring higher capital and operating costs while each has They have been used to optimize mineral processing in Au Ni Fe Ore Cu coal Al At one US gold mine in Nevada a portable TERRA XRD analyzer has been used to of oxides to the acid leach circuit and sulfides to the flotation circuit will influence the volumes of acid consumed and directly affect processing costsThe process flow sheet at Newmont Boddington Gold NBG comprises primary cyclone overflow is treated in a flotation circuit that produces a copper gold
