Flotation Froth
However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.
inorganic chemistry
Copper sulphate had no significant effect on the rate of adsorption of potassium n-butyl xanthate (PNBX) onto pyrite. Copper adsorbed irreversibly onto the pyrite when the latter was slurried in a copper sulphate solution. Copper sulphate had a significant effect on the maximum froth height obtained in static three-phase froth tests.

Activators- Chemistry By Unacademy
Copper sulphate and sodium sulphide are the two common activators used in the froth floatation process. Copper sulphate is used for sphalerite, which is also known as zinc sulphide since its presence increases the air bubble-mineral interaction, enhancing the hydrophobic nature. Froth stability largely affects the process.
Flotation Depressants
For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color. This is because the froth is becoming purer as the unwanted mineral, the iron pyrite, is being cleaned off of the bubble.
