Flotation process of black tungsten ore

Common minerals wolframite wolframite ore iron (Fe, Mn) W04, Ferberite (FeW04) manganese, and tungsten (MnW04). They are isomorphic minerals. The order of floatability of these three minerals is:

Tungsten manganese ore>tungsten manganese ore>tungsten iron ore

Commonly used collectors for flotation wolframite are oleic acid, sulfosuccinic acid, benzoic acid and phosphonic acid. Salicylic acid is also a promising collector for floating black tungsten. Oleic acid has a strong catching power, but its selectivity is poor.

The pH of the wolframite flotation with oleic acid is similar to that of scheelite , with sodium carbonate as a regulator. Flotation of wolframite with benzoic acid or phosphonic acid is carried out in an acidic medium, and the regulator is sulfuric acid or hydrochloric acid. Lead nitrate is commonly used as an activator.

Flotation gangue inhibitor wolframite wolframite are: sodium fluoride, a mixture of water glass, sodium silicate and aluminum sulphate (6: 1), heavy chromate, sulfuric acid and hydrofluoric acid . However, the wolframite itself can be inhibited by a large amount of chemicals such as leather acid, sodium fluorosilicate (4 kg/t or more) and water glass, so the amount of the inhibitor must be strictly controlled.
