Celanese - The chemistry inside innovation

Flotation – A flotation frother – like Methyl Isobutyl Carbinol, 2-Ethyl Hexanol, or terpenic oil – and a "slurry" of fine powder and water are then introduced to a water bath (i.e., flotation cell) which is aerated, creating bubbles. Frothing – A stable froth is formed on the surface of the flotation cell from the aeration.

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.
