floatation for gold and copper

Optimisation of gold recovery by selective gold flotation ...

2001-2-1  The aim of the testwork was to optimise the free gold recovery by; (1) enhancing the copper and gold recovery into a copper concentrate and (2) floating the gold away from the copper sulphides and pyrite. The ore was crushed to -2 mm and ground in a stainless steel laboratory rod mill to a p80 of 106 ~tm for the flotation tests.
