  • Ion Flotation Of Rhodium Iii And Palladium Ii With

    mar 01, 1991 the ion flotation of rhodium and palladium with some anionic surfactants has been investigated. two flotation procedures are proposed for the separation of some platinum metals, based on differences in the kinetic properties of the chloro-complexes of rhodiumfor the recovery of rhodium from primary sources, ores are generally crushed, finely ground and then treated by flotation and magnetic methods to separate sulphide minerals. these sulphides are further separated to yield a nickel concentrate which contains most of the platinum metals.

  • Recovery Of Platinum Group Metals From Oxide Ores Tml

    the great dyke, zimbabwe, contains over 800 million ounces of platinum and approximately million ounces of rhodium. however, about 10% of the ore is oxidized and cannot be processed with current recovery methods. conventional flotation-smelting process has been proposed to recover the platinum group metal values from the sulfide ores.may 30, 2016 introduction. flotation is usually employed to remove silicate as the main impurities from many ore types, especially iron ores. iron oxides can be concentrated either by direct flotation, using anionic collectors, or reverse flotation of siliceous gangue with both cationic and anionic collectors .studies showed that the flotation recovery and selectivity was significantly higher in

  • Treatment Of Platinum Flotation Products Johnson Matthey

    flowsheet has been developed for the production of rich concentrates of precious and non-ferrous metals by a complex treatment of the flotation products from south african platinum-containing chrome ores. the procedure involves: autoclave leaching, roasting, hydrochlorination and precious metal recovery by sorption. autoclave oxidative leaching of the initial material allows the non-ferrous provided is a method involving flotation of a feed of platinum group metal ore material to prepare a platinum group metal concentrate during mineral processing operations. prior to andor during the flotation, a lead-containing activator reagent and a xanthate collector reagent are added to the slurry and during the flotation, an oxygen-deficient flotation gas, such as nitrogen gas, is used.
