How to control the amount of flotation reagent?

Flotation agents are a major factor in regulating the floatability of minerals. Insufficient dosage can not be adjusted, minerals are difficult to select; excessive dosage can also cause adverse effects, not only reduce concentrate quality, loss of selectivity, but also waste. In fact, only a small amount of collector can be added to the flotation to form a hydrophobic film on the surface of the mineral. The amount of the same inhibitor and activation of a certain mineral is also very small . Therefore, in actual use, special emphasis should be placed on " appropriate amount ". And " selective " .
