platinum ore processes
BARNES 2005
The process of percolation of dense, low-viscosity sulfide liquid into pore space and fractures within partially molten (or melting) silicate rock is a unifying theme that links sulfide matrix ore breccias and emulsion textured ores with distinctive textures in less sulfide rich rocks such as net-texture (matrix ore texture), leopard texture ...

Native Platinum
Platinum luster is metallic; its hardness is 3.5-4.5. Platinum streak is silver-grey and shiny; and its density is extreme at 21.45, but decreases to less than 20 near its melting point of 1769ºC. Impurities in natural native platinum lower its density to 14-19, and iron impurities may impart a slight level of magnetism. Fluorescence is absent.

In the case of mantle-derived magmas, a high degree of partial melting of the mantle serves to enrich the silicate magma in Ni and platinum group elements (PGE). This magma must then be transported to the crust by an efficient process in order to reduce the possibility that Ni is removed from the magma by crystallization of olivine.

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.
