froth floatation of purification

Copper extraction Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant. Sulfide smelting

Separation and purifiion of carbon nanotubes using

Mar 11, 2013 · Carbon nanotubes (CNTs) with a carbon content of 3% were synthesized via the disproportionation of CO over a CoMo/SiO 2 alyst. The proposed purifiion technique consisted of four sequential steps: oxidative treatment, acid leaching, silica dissolution, and froth flotation.

Scaleup in froth flotation: A stateoftheart review

Froth flotation works on the basis of surface chemistry fine mineral particles are separated according to their hydrophobicity. This separation process disperses small bubbles of gas, generally air, inside a flotation tank, also referred to as flotation cell. The tank contains a mineral suspension in an aqueous media, called the pulp.
