Effect of Collector & Frother Concentration on Copper Flotation
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.
