In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve reserves of about 2500 metric tons [2]. Platinum group metals or elements commonly refer to ruthenium, rhodium, palladium, osmium, iridium, and platinum and will be referred to as PGEs in the present paper. These metals are present in a very wide range of platinum group minerals, which will be referred to as PGMs. Table1shows the 2018 productionThe Geological Occurrence, Mineralogy, and Processing by Flotation

One of the stages of extracting gold and platinum from sulfide materials and circulating slags is the melting stage in ore-thermal and electric furnaces, where the melt is separated into matte and slag. Gold, platinum, and non-ferrous metals are concentrated in the matte. However, a significant portion of them ends up in the slag, which reduces In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals.

presence of various concentrations of xanthate. Flotation behaviour of gold associated in the platinum group metals is apparently the same as that for the platinum group minerals (PGMs) or other minerals associated with the PGMs (i.e. nickel, pyrrhotite, copper and pyrite). Therefore, the reagent scheme developed for PGMs also recovers gold.Concentration by froth flotation was investigated by the Bureau of Mines because the platinum-group-bearing sulfides occur as fine grains and require grinding to approximately 200 mesh for liberation. Recovery of 80 to 90 pct of the Pt-Pd values was achieved from an acidified pulp with a mercaptobenzothiazole collector.Recover PGM by Matte Smelting and Leaching 911 Metallurgist

On the Management of Gangue Minerals in the Flotation of Platinum
The Bushveld Complex of South Africa contains almost 90% of the world’s reserves of platinum group minerals (PGMs). In the flotation of PGMs, there are significant challenges arising from the need to treat ever-decreasing grades of the relevant ore deposits. The major challenge in the flotation of these ore bodies is the control and Russia and South Africa are the world’s leading producers of platinum group elements (PGEs). This places them in a unique position regarding the supply of these two key industrial commodities.

At high concentrations, the Ca 2+ and SO 4 2− may negatively affect the flotation response of the Merensky ore, resulting in the observed lower mass pull and recovery of valuable minerals. SO 4 2− may promote the oxidation of sulphide minerals, the formation and precipitation of metal sulphate on minerals surfaces, as well as the concentration in the concentrate is less than ¿ 3% so that it does not negatively impact the A further problem when considering fine particle flotation is that the large specific and cubanite.

The following briefly discusses several different ores: those amenable to gravity separation, those amenable to flotation, and those where platinum-group elements are by-products of base metal sulphides.The South African platinum industry has advanced into an era of predominantly mining and processing Upper Group Two (UG-2) ore to extract Platinum Group Metals (PGMs).
