Froth flotation process - The Dow Chemical Company

Froth flotation is a commonly employed process for concentrating minerals from ores. In a flotation process, the ore is crushed and wet ground to obtain a pulp. A frothing agent, usually employed with a collecting agent, is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent ...

Write the principle behind the froth floatation process ...

Froth floatation process is based on the principle that the metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. Collectors attach themselves by polar groups to grains of minerals which then become water repellent and thus, pass on into the froth.

What is the role of depressant in froth floatation process?

Depressants prevent certain types of particles from forming froth with bubbles. Due to this, we can separate two sulphide ores. For example, sodium cyanide is a depressant used for an ore containing Z nS and P bS. N aC N forms a layer of the complex N a2. ] on the surface of Z nS and prevents it from forming a froth. Thus, it acts as a depressant.
