Benefits Of Flotation Gold

beneficiation of the gold bearing ore by gravity and flotation,on the other hand, a gold concentrate about 82 g/t is obtained with 89.9wt% recovery from a gold ore assaying 6 g/t au by direct flotation. the choice among these processes beneficiation of the gold bearing ore by gravity and flotation | springerlink.a review of the flotation of native gold and electrum,appropriate reagents could then be used to depress the pyrite, e.g. hydrogen peroxide as suggested by monte et al. (1997), and then float the gold. there could be advantages in doing this, such as reducing the gold content of a concentrate going to a roaster, but the advantage may be small and this does not seem to have been attempted commercially..

Mineral Flotation - International Mining

“flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. if the ore contains a low amount of iron sulphides, xanthate collectors are often suitable to float copper sulphideminerals. if native gold is present, dithiophosphates can be used which are less selective to iron sulphides.
