Marco, If you are floating sand from fibrous silicates, you are really floating silica away from silicates. the floation of silica is usually done at very low pH (2) and you use petroleum sulfonates to float the silica. The problem you have here is that the fibrous silicates will cause rheology problems in the pulp.

A process of purifying silica sand comprises grinding sandstone, washing and desliming the ground sandstone to remove the major part of the clay-type binder, attrition-scrubbing the deslimed sand particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the sand particles, treating the hot …

However, if silica sand and graphite are first placed in water and then oil is added, the silica sand will remain preferentially wetted by water while the graphite will preferentially be wetted by oil. This is essentially the mechanism of action of water-insoluble oils in the froth flotation of naturally hydrophobic minerals.

The sand is then sent to the wet process area, where it is sized in centrifuges, washed in screw classifiers and scrubbers, cleaned of fines and clays using rake classifiers, and cleaned of iron by chemical flotation. The sand then passes through a hydrocyclone, is dewatered by vacuum filtration, and transferred to the damp storage tanks.

Flotation is mainly used to separate feldspar from silica sand, and can also be used to remove clay minerals such as mica and secondary iron from silica sand. The most typical process is to use hydrofluoric acid as the activator, and use an amine cationic collector for flotation under strong acidity (pH=2～3).
