Frothing In The Flotation Of Copper Sulfide Ores Ore Mining Problem. The ore is a sulfide copper ore containing heads of approximately copper 0 45 iron 3 4 molybdenum 0 006 and zinc 0 06 per ore sample Prior flotation of this ore has employed in the floation cell the addition of pine oil as required to optimize froth ordinarily resulting in a total pine oil concentration of about 0 24 lb tonFrothing in the flotation of copper sulfide ores in sea,,Request PDF | Frothing in the flotation of copper sulfide ores in sea water | The selection of appropriate frothing agents for flotation of porphyry copper ores in sea water is becoming an,Froth flotation - Wikipedia,Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a…
