A process for treating chromite bearing ores to obtain useful mineral values especially platinum group metal therefrom wherein the ore is separated into magnetic and non magnetic fractions; the non magnetic fraction containing a substantial portion of the platinum group metals is concentrated and smelted to produce a metal layer containing platinum group metals; and the
The process of depositing platinum group metals onto the γ Al 2 O 3 surface involves impregnation using solutions containing South African ores contain an average of around 3 4 g of platinum group elements per ton of ore Table 5 Minerals containing PGM Sulfides Braggit Pt Pd S cooperite PtS laurite Ru [Os Ir]S 2 and unnamed Pt Rh
Ore Processing Once the ore is extracted it is transported to a processing plant for further processing Platinum ore is typically processed through a series of crushing grinding and flotation steps to separate the valuable platinum minerals from the gangue minerals Additional processes such as gravity separation magnetic separation or
The platinum group metals PGM include ruthenium Ru rhodium Rh palladium Pd osmium Os iridium Ir and platinum Of these elements only platinum and palladium are found in a pure form in nature The others occur in nature as natural alloys with platinum and gold for example

Platinum Analysis Ore Grades & S African PGM Mines Geological Structure Part II by Dr David Davis Home » Platinum Analysis Expansion is constrained by infrastructure and processing capacity which will require additional capex In my view the projects described above will unlikely stem the falling mine supply in the longer
The positive outcome of a mixture design in mineral processing can be seen from a laboratory study performed by van Tonder et al 2010 where they studied the effect of ore blends in platinum
Platinum were used as the basis to plan the expansions that were required to exploit the UG2 ore at Eastern Platinum An innovative approach to UG2 processing that was used in the Eastern Platinum plant design was the introduction of the mill float mill float MF2 concept and the removal of a chromite fraction from the primary rougher tail Both
