Abstract— A study on physical beneficiation of platinum group metals (PGMs) flotation tailings was carried out by means of spiral classifiers and a gravity separator (Knelson Concentrator KCCVD – 6 unit). The economic mineral reserves for PGMs are found in the ... associated with metal oxides and sulphides while PGMs
