Sulphide Flotation - an overview | ScienceDirect Topics

In most flotation plants, sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation. Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetra-auricupride [AuCu] relative to native gold. At the Kemess flotation plant depending on the ...

As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...

Copper extraction - Wikipedia

Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals.
