Chalcocite Flottation

Selective Flotation of Chalcopyrite and Pyrite from a Mixed …

A process that allows selective flotation separation of low Cu/S ratio minerals (chalcopyrite and pyrite) from high Cu/S ratio minerals (bornite and chalcocite) from a mixed copper …

A fundamental study of chalcopyrite flotation in sea water …

Flotation experiments showed significant depressing influence towards chalcopyrite flotation at pH 10 in sea water and 0.05 M MgCl 2 solution, mainly due to …

The Life Cycle of Water Used in Flotation: a Review

In order to mitigate the negative effect of clay minerals (e.g., kaolinite) on copper-bearing minerals such as chalcocite flotation, Zhao and Peng investigated the effects of saline water. The results showed …

Enhancing flotation separation of chalcopyrite and …

The micro-flotation experiments and zeta potential measurements showed that combined depressant consisting of PAAS and GA could efficiently reduce the …

The separation of chalcopyrite and chalcocite from

Flotation tests of pure and mixed minerals indicated that H2O2 treatment reduced the floatability of chalcocite and enargite by forming sulfate and copper …

Chalcopyrite or chalcocite recovery as a function of flotation …

Flotation, as a supplementary approach, can be used to separate fine zircon from heavy minerals (i.e. rutile, cassiterite).

Effect of oxidation treatment on the selective separation of

The findings showed that the H 2 O 2 treatment selectively depressed chalcocite flotation by producing copper hydroxide and sulfate species on the chalcocite …

CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

The complete flotation of chalcocite is achieved between ph = 1 to ph = 10 with ethyl xanthate. The resulting hydrophobic species is CuX. Hydroxyl as depressant (OH-) …

The separation of chalcopyrite and chalcocite from pyrite in …

Chalcopyrite and chalcocite do not affect pyrite flotation in the same way in rougher flotation after primary grinding. This is because the galvanic interaction between …

Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review

Nowadays, froth flotation of chalcopyrite ore has developed a large number of reagents that make it possible to improve the mineral's buoyancy conditions, …
