Recovering Gold through the Froth Flotation Process

Feb 06, 2018· Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Froth flotation cell level measurement VEGA

To work efficiently, flotation cells depend on continuous froth formation. If the froth layer is too thin, it cannot transport the sufficient amount of dispersed or suspended particles to the surface. On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long.

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 ofplex N a2. on the surface of Z nS and prevents it from forming a froth. Thus, it acts as a depressant.
