characteristics of the ore—complex ores may contain lead, zinc, nickel and other metals—and whether facilities are in place for capturing and converting the SO2. Sulfur dioxide emissions may range from less than 4 kilograms per metric ton (kg/t) copper to 2,000 kg/t .

During the initial stages of sulphide operation, high copper (Cu)low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 9195% recovery was produced utilizing a highpH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn of the ore body, a Cu/Zn separation circuit was initiated in early ...

The ore is a sulfide copper ore containing heads of approximately: copper, iron, molybdenum, and zinc 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 lb./ton.

01/10/2003 · A twodimensional dynamic model for bioleaching of secondary copper minerals from a pile has been developed. In the model, aeration of the pile is considered to be due to natural convection caused by the density gradient in the air within the bed. The rate of sulphide mineral dissolution is modelled according to the unreacted core model.
