May 08, · Once on the surface, the ore is crushed and milled in order to obtain smaller rock particles and to expose the minerals which contain the PGM (Platinum group metals – gold, platinum and palladium). In a "froth flotation" process these particles are mixed with water and special reagents, before air is pumped through the liquid.

Froth Flotation ProcessDetailed Explanation With

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively.
