The flotation of gold bearing ores — A review - …

When selectivity is required or, in the case of copper gold ores, where a copper concentrate is sold to a smelter, a weaker frother such as MIBC is used [47,48]. ACTIVATORS In gold flotation these are soluble base metal salts where the metal ion adsorbs onto the mineral surface thus changing its surface chemical properties.

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 gold's hydrophobicity. This mixture is placed into a large tank filled with distilled water.
