    Abstract: This invention is related to a methodology to determine flotation performance of sulphide ores. The objective of this invention is to develop a quantitative measure of surface oxidation to estimate flotation behavior of sulphide ores. 10 grams of ore samples are treated with hydrogen peroxide solutions to change their degree of surface oxidation (Figure 1). The same procedure is applied using 1 kg ore for batch flotations. For each conditions EDTA tests and batch flotation test are performed. The relationship between surface oxidation and cumulative copper recovery (%) for Cayeli Cu-Zn sulphide ore is given in Figure 3. For each test ultimate recovery and flotation rate constants are calculated.

    Abstract: A method of controlling operation of a froth flotation cell comprises introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, which froth overflows and leaves the cell at an overflow point, wherein the froth has a froth height from the level of the overflow point to the upper surface of the froth, measuring values of the froth height for two values of gas flow rate into the cell, measuring values the velocity at which the froth overflows at the overflow point for two values of gas flow rate into the cell, calculating a gas flow rate into the cell that optimises gas recovery, by treating the measured values of froth height and measured values of froth velocity independently, and setting the gas flow rate into the cell to be the calculated flow rate into the cell that optimises gas recovery.
