What is the role of pulp temperature in the flotation? Why does temperature have little effect on xanthate?

Floating pulp temperature increase beneficiation, flotation can increase the speed and get a higher flotation (recoveries and concentrate quality).

Slurry temperature also has an effect on the action of activators and inhibitors. In general, when the temperature rises, the activator and the inhibitor act strongly and accelerate, and when the temperature is lowered, the effect is weaker and slower, and the flotation index is lowered.

In the flotation of some difficult to float non-ferrous metal oxide ore, in order to promote the vulcanization of sodium sulfide, pulp often require heating, non-metallic mineral flotation, greater temperature.

Some plants have seasonal fluctuations in some technical and economic indicators of the concentrator due to the large difference in slurry temperature between winter and summer.

Due to the large amount of pulp in the concentrator, it is not economical to heat a large amount of pulp in order to adjust the temperature. Therefore, the general flotation process is carried out at room temperature.

Why does temperature have little effect on xanthate? Mainly because the yellow medicine is in the flotation, because it is easily soluble in water, the temperature has little effect and does not need to be heated.
