Pyrite Depression in Copper Flotation

08-10-2015· Pyrite Depression in Copper Flotation The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant’s pH up to the other side (right side) of the PYRITECopper and Pyrite Separation by Selective and Sequential,,13-04-2016· Flotation process of Copper-Pyrite minerals The flotation section is composed of two 8-cell “Sub-A” Flotation Machines. The copper section has four rougher cells, two scavenger cells and two cleaner cells for dual cleaning of the rougher concentrates.Recovery of pyrite from copper tailings by flotation,,01-09-2019· The recovery of pyrite at 5 min of flotation is 97.8%, and at 7 min of flotation the maximum estimated recovery of 99.1% is reached. In order to produce a concentrate with a pyrite grade closest to 90%, and a recovery above 90%, 3.5 min were selected for the recleaner flotation stage as the optimum flotation time. 3.3.

Pyrite Depression In Copper Flotation

Pyrite Depression In Copper Flotation. A review of the considerable, but often contradictory, literature examining the specific surface reactions associated with copper adsorption onto the common metal sulfide minerals sphalerite, (zn,fe)s, and pyrite (fes(2)), and the effect of the co-location of the two minerals is presented. copper a.Quipment Copper Pyrite Mineral Flotation,Pyrite Flotation Magma Copper Companys Superior.

The three biopolymers displayed different depression abilities. At a concentration of 33 mg L −1 , DP-1775 and DP-1778 decreased pyrite recovery to 21.4% and 23.4%, respectively, while only a slight decrease in pyrite recovery was observed with DP-1777.

Comparing lead and copper activation on pyrite with,

01-07-2021· In the flotation of copper/lead-activated pyrite, xanthate mainly interact with copper/lead ions on pyrite surface, forming Cu(Ι)-X/Pb(OH)X/PbX 2 (Sui et al., 1997, Chandra and Gerson, 2010). As a result, the amount of Cu/Pb ions on pyrite surface is expected to reflect the extent of xanthate adsorption and pyrite flotation ( Finkelstein, 1997 , Peng et al., 2012 , Yang et al., 2016 ).Copper Flotation - Mineral Processing & Metallurgy,16-05-2016· When pyrite is present, lime performs the additional function of a depressor, the amount used being balanced against that of the promoter—that is, no more lime should be added than is required to prevent the bulk of the pyrite from floating, as any excess tends to depress the copper minerals, and no more of the promoter should be employed than is needed to give a profitable recovery of the,A study on selective flotation in low and high pyritic,,impact of pyrite on copper flotation.
