The future of flotation

The future of flotation

Nov 04, 2016 Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons

A twostage bacterial pretreatment process for double

Jan 01, 2005 Double refractory gold concentrates were subjected a two-stage microbial process to destroy both sulfides and carbonaceous matter. In the first stage, the well-known sulfide biooxidation process, which utilizes chemolithotrophic bacteria was used to oxidize sulfides and in the second stage carbonaceous matter is destroyed using the bacterium Streptomyces setonii.

Separation Efficiency Improvement of a Low Jameson

Once the ore has been ground and a size distribution of particles is presented to a flotation cell, the only parameter that can be manipulated to reduce the entrainment is water recovery. If additional water is added to dilute the contents of the flotation cell, and the flow rate of water to the concentrate remains the same, the water recovery will

The Causes for the Poor Flotation Performance of a Double

The Causes for the Poor Flotation Performance of a Double

The recovery of gold from certain Carlin-type deposits, with numerous perceived and real recovery problems is quite challenging. These deposits are characterised as double-refractory because most of the gold values are locked in sulphide minerals (e.g. pyrite and arsenopyrite) and, therefore, cannot be leached directly with cyanide pre-concentration of sulphide minerals by flotation ...

Nov 01, 2011 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.
