Improved depression of talc in chalcopyrite

05.12.2018· As talc has a strong natural hydrophobicity, it can easily float in the foam product during chalcopyrite flotation, thereby dramatically increasing the Mg content in the flotation concentrate [2,3]. Therefore, the effective inhibition of talc during chalcopyrite flotation has become the key to efficient exploitation and utilization of such copper resources.

Flotation Behavior of Malachite Using

In this study, the flotation behavior of malachite was investigated using hydrophobic talc nanoparticles (TNs) as collectors. To improve the floatability of TN-deposited malachite, various experimental parameters were systematically investigated. We found that the floatability sharply increased as the size of the TNs decreased. The floatability of malachite was enhanced in the presence of

Talc Mining | Processing Equipment | Flow Chart |

Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).
