Chrysocolla Flotation By The Formation Of Insoluble Surface

To function as a flotation collector the chelating functional group must be a part of a sufficiently long hydrocarbon chain so as to impart hydrophobicity to the mineral on adsorption. The resulting chelate should preferably be neutral complex because neutral complexes are usually insoluble in water and therefore promote hydrophobicity.

Fluoride Activation In The Flotation Of Chromite Abido

Hydrofluoric acid was shown to have good selective properties in amine flotation of chromite that qualify it as a possible flotation reagent. It seems that hydrofluoric acid could be adsorbed strongly and preferentially on the chromite surface to give the extremely insoluble CrF 2 − ion that exhibits great affinity for the positively charged .
