Gold Flotation Mineral Processing Metallurgy
Pneumatic cells use no mechanical agitation (except the Macintosh, now obsolete) and depend on compressed air to supply the bubble structure and to hold the pulp in suspension REAGENTS USED IN FLOTATION OF GOLD ORES In the treatment of an auriferous sulphide ore associated with carbonaceous shale from South Africa Flotation is routinely used for the beneficiation of platinum ores for which the bulk of world production is from South Africa Most South African platinum concentrators use mechanically agitated flotation cells which operate with power intensities higher than the typical industrial range of 10–20 kW/m 3This is due to the general philosophy in the platinum industry that increasing power The effect of agitation on the flotation of platinum ores Application of flotation on a reasonable scale within the goldmining industry commenced in the early 1930s following the introduction of watersoluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals, followed by the installation of pyrite flotation plants on numerous gold mines in South AfricaFlotation of Gold and GoldBearing Ores ScienceDirect
The effect of agitation on the flotation of platinum ores
Flotation is routinely used for the beneficiation of platinum ores for which the bulk of world production is from South Africa Most South African platinum concentrators use mechanically agitated gold ore of South Africa The flotation of the uranium each ore type under identical conditions in a 2L Agitair cell Test conditions such as agitation (600 rpm), aeration (6 levels in concentrates of gold only ores, RY1 and SYW1 are low (less than 50 ppm U) compared to the copper oresLaboratory Flotation Characterisation of a Uranium The behaviour of free gold particles in a simulated flash flotation environment by TDH McGrath*, JJ Eksteen*, and J Heath† Synopsis A reliable laboratory method to characterize the response of free gold particles to flash flotation conditions has been developed The test has been performed on free milling gold ores as well as synthetic The behaviour of free gold particles in a simulated flash

flotation research has indicated TTCs to be very effective sulphide mineral collectors1 They are currently used in the flotation of copper ores in the USA and Spain and gold ores in South Africa Essentially the difference between the two reagents is the three bivalent sulphur atoms bound to the carbon atom of the functional Flotation Procedure For each test, approximately 50 g of ore and 650 ml of water were placed in the cell Selective flotation of pyrite and gold tellurides 331 The pulp was then conditioned for 3 minutes at the desired pH level For modifying the pH of the pulp, sodium hydroxide and sulphuric acid were used After 3 minutes of conditioning, the Selective flotation of pyrite and gold tellurides Imhoflot™ Pneumatic Flotation Technology has evolved through 25 years of industrial applications The development of the patented Imhoflot G and HCells followed, reducing the size of vessels considerably by using centrifugal forces in the cell to rapidly Maelgwyn – Mineral Services Africa (Pty) Ltd
