  Gold Extraction amp Recovery Processes 911 Metallurgist

  Chemical composition of gold particles and associations with other minerals affect gold recovery by flotation. In general, gold-pyrite or gold-copper minerals associations have no problems and gold can be recovered without major problem. The lack of good liberation is a problem and the comminution circuit is the key element.

  Pyrite Flotation Froth Flotation Sulphide amp Oxide

  From my understanding, you would like to get a high pyrite flotation recovery because the gold is locked in the pyrite. And you are trying to analysing the effect of various factors on pyrite flotation. I would suggest: 1.It will be good to find out the optimum particle size firstly.froth flotation with thionocarbamate. You mentioned 70um and 150 um.

  Gold Flotation 911 Metallurgist

  Jul 13, 2016 A gold carbonaceous sulphide ore from California carrying free gold yielded a 93 per cent recovery into a concentrate at 14.4:1 to ratio of concentration after conditioning with 0.50 lb. per ton of reagent 645. In each case the ore was ground to about 70 per cent minus 200 mesh and conditioned at 22 per cent solids with the reagents as indicated.

  Jan 01, 2016 These collectors are selective against pyrite at pH values 10 and afford savings in lime and improved gold recovery when treating copper–gold ores with reasonable contents of pyrite (Dunne, 1991). Amine-based collectors have been used to float gold and gold-bearing pyrite (Levin and Veitch, 1970). The application is limited as the amine collector is selective for pyrite at high pH values …
