Abstract
A method of recovering gold and copper from a sulfide ore includes (a) removing valuable fines from a product stream from a comminution circuit, such as a crushing and milling circuit, for run of mine ore and producing a valuable fines concentrate stream and (b) processing the remaining comminution product stream after valuable fines removal and producing a valuable coarse concentrate stream.
Claims15
A method of recovering gold and copper from a sulfide ore, the method comprising:
- (a) comminuting the sulfide ore and producing a comminution product stream;
- (b) removing fines from the comminution product stream by passing at least a part of the comminution product stream directly from (a) through a fines flotation element and producing therefrom only two streams (i) and (ii):
- (i) a valuable fines concentrate stream comprising a valuable fines material, and
- (ii) a coarse flotation feed stream comprising a valuable coarse material, a waste coarse material, and a waste fines material;
- and
- (c) removing valuable coarse particles from the coarse flotation feed stream by passing the coarse flotation feed stream through a coarse flotation element and producing a valuable coarse concentrate stream and a tailings stream.
