The Guide of Flotation Defoamers cnlitereagent

2020-3-5  Flotation agents are chemical agents used in the mineral flotation process which can adjust the surface properties of the minerals, increase or decrease the floatability of the minerals, and make the pulp properties and foam stability more conducive to mineral separation. Common flotation agents are collectors, foaming agents, inhibitors, activators, dispersants, flocculants and defoamers.

Under normal circumstances, if the amount of foaming agent exceeds the standard, the foam in the flotation machine will be too much, too large, and sometimes even the foam will be too large to reflect on the surface. On the contrary, the amount of foaming agent is not enough, and the foam in the tank will be reduced.
