- platinum palladium and rhodium flotation machine
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.

platinum, palladium, and rhodium, collectively known as 4E. Nickel and copper are the most prevalent base metals in sulphide ores containing PGMs. Chromite (used to derive chrome) is another significant by-product while cobalt, silver, selenium, and tellurium are found and recovered in trace quantities [11]. Most deposits contain 1–5 g/t 4E [8].
