Platinum-group element concentrates are made into a matte that is relatively low in iron and sulfur, and enriched in platinum-group elements by smelting and converting. Smelting removes most gangue minerals as molten slag. Converting removes most iron and sulfur by oxidation with air and oxygen. In combination, these two steps upgrade the feed ...

platinum group metals from other ores in the final stages of refining does not make the rock platinum ore. Although no one can predict the future, the present knowledge of the geology, mineralogy and economics of platinum and Arizona are not conducive to the discovery of producible quantities of platinum group metal ores in Arizona.
There are large deposits of platinum group elements in the Merensky and Upper Group 2 reefs in South Africa ("South Africa"). These deposits were formed from silicate magma intrusions. Immiscible sulfide …
In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of ...
2. Literature review on platinum-group minerals 2.1. Platinum-group element mineralogy 2.1.1. Introduction The distribution of PGEs (platinum-group elements) in an ore is directly related to the type of ore, which in turn, dictates the mineralogical constitution. PGE ores …
