Gravity concentration, froth flotation, roasting and leaching are the three primary routes discussed in the literature. Among all the methods, flotation has gained the attention of most researchers because of its cost economics [35]. The effectiveness of the flotation process relies on the choice of the suitable type and dosage of surfactants.

A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.

The ultimate goal of a flotation process is to achieve the economically optimum combination of the desired mineral grade and recovery in the final concentrate from a feed of varying composition. The industrial operation of froth flotation faces many challenges, such as sudden decreases in the recovery and grade of recovered materials.

3. Xanthate Application in Copper Froth Flotation. In the flotation process of copper ore, xanthate mainly reacts with Cu2+. Therefore, when processing minerals containing more Cu2+ on the surface, the effect of xanthate is stronger, and the order of its action is: Cu2S > CuS > Cu5FeS4 > CuFeS2. 4.
