Rougher flotation of copper sulphide ore using biosolids ...

2011-11-1  1. Introduction. Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulphide minerals (Herrera-Urbina, 2003).This process is based on the wettability of mineral particles to recover the mineral species of interest and depress unwanted gangue.

2021-11-24  The flotation ORP normally is from - 500 mV to - 600 mV, depending of the Copper Sulphide species. Depending of the pH you will have H2S gas emmision to the ambient that you can have controlled in float cells closed and with scrubbers with caustic solution (10%) achieving in some cases close to approx 0 ppm of H2S to the plant site ambient.

The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.
