  • ReProcessing Gold Tailings in South Africa

    The pyrite concentrate will be treated by high temperature pressure oxidation (POX) in this flowsheet, to oxidize the sulphides to sulphates (mainly ferric sulphate and sulphuric acid) and liberate any gold and uranium locked in the pyrite Uranium leaches under the oxidizing, acidic conditions prevailing in the autoclave, while gold remains in  In South Africa more than 60 million tonnes of dry ore are processed annually in flotation plants to recover auriferous pyrite One of the main reasons for floating the pyrite is to produce a feedstock for the manufacture of sulphuric acidThe practice of pyrite flotation in South Africa and   processing flowsheet selected is well known in South Africa and considered commercially favourable There are at least three operations making use of this process – including Glencore’s Rhovan and Evraz’s Vametco operationsBUSHVELD MINERALS LIMITED
