Effect of grinding media and NaHS on copper

2000-11-1  The flotation behaviour of copper minerals in the Northparkes Mines copper-gold ore is dependent on grinding media (and hence grinding Eh) and aeration during conditioning. Laboratory grinding and flotation tests were conducted using mild steel and stainless steel rods with and without the addition of sodium hydrosulphide (NaHS) in the conditioning stage.

Copper Flotation - 911 Metallurgist

2016-5-16  Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper

Copper Mines - an overview ScienceDirect Topics

In the Aitik copper mine a raised specific charge from 0.9 to 1.3 kg/m 3 gave rise to an increase in the throughput by nearly 7% due to more fines produced and shorter grinding time achieved [28]. Similarly, a high specific charge from 2 to 3.0 kg/m 3 resulted in an increase in the mill throughput by 20–40% [29] .
