platinum froth flotation

The Properties and Applications of Platinum

 · The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water a process known as froth flotation . During flotation air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.

 · The Bushveld igneous complex in northern South Africa has the largest deposit of platinum group elements (PGE) in the world. In trace amounts these are closely associated with base metal sulphides (BMS). Froth flotation is used to beneficiate these PGE ores. The process constitutes a bulk sulphide recovery.

1 Froth FlotationFundamental Principles

 · 1 Froth FlotationFundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

 · 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 metalsgold platinum and palladium). In a "froth flotation" process these particles are mixed with water and special reagents before air is pumped through the liquid.

The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
