· This paper reports an innovative development: concentrating gibbsite via reverse froth flotation in order to obtain a metallurgicalgrade bauxite concentrate. Tailings from an industrial plant have undergone attrition scrubbing and desliming; the quartz silica contained in the tailings has undergone flotation. Starch was used as a depressant, and etheramine as the ionic collector. .

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...

Marco, If you are floating sand from fibrous silies, you are really floating silica away from silies. 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 silies will cause rheology problems in the pulp. So you will need to add a dispersant like polyphosphate or acrylate ...
