The flotation separation of galena and pyrite using

2019-1-15  The effect of PBX concentration on the flotation performance of different-sized galena and pyrite at pH 7 is studied and the results are shown in Fig. 2.As shown in Fig. 2, the flotation recoveries of these two minerals increased quickly with the increase of PBX concentration.When PBX concentration reaches 0.5 × 10 −4 mol/L, the recoveries for both galena and pyrite reach their maximum values.

Pyrite Depression in Copper Flotation

2020-6-25  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 PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite

Pyrite Depressant on copper ore Froth Flotation

2020-7-5  Flotation of copper at different alkaline pH from 7 up to 10 and using different Xanthates as collector vs recovery of copper may give some clue. Minimum Pyrite obtained in copper concentrate is the starting point for further flotation testwork. Depressing Pyrite is always a tricky matter.

Flotation Depressants Mineral ProcessingMetallurgy

2020-6-25  First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as

Pyrite Depressant Froth Flotation (SulphideOxide

2020-7-15  Of course, there are other depressants for pyrite (more selective). The world of the flotation reagents has changed. Now there are a lot of good new reagents on a commercial scale. Aeration The surface of the pyrite oxidizes rapidly and it floated worse. At the same time at a short aeration of the pulp extraction of copper increases.

The depression of pyrite in selective flotation by

At low xanthate concentrations, pyrite flotation presents two maximums at around pH 4 and 8 with depression around pH 7. The high flotation yield at pH 4 is due to the formation of sulfur-rich products and dixanthogen (Leppinen, 1990, Wang and Forssberg, 1991, López Valdivieso et al., 2005).

Pyrite Tailings Recovery by Flotation

2020-6-25  Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a

They demonstrated that the pulp oxidation potential is one of the important factors controlling the copper-activated pyrite flotation so that it can determine the different proportions of hydrophobic and hydrophilic species on the pyrite surface (He et al., 2005).

Impact of recycling cyanide and its reaction products

2013-11-1  Effect of anions on flotation of pyrite (after Sutherland and Wark, 1955). Of particular interest to copper–gold plants is the more significant depressant effect of the iron cyanide complexes on the flotation of copper minerals, such as chalcopyrite and chalcocite, as shown in Fig. 9 .
