Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O''Meara, 1939).
Jan 15, 2008· Reverse flotation of hematite from a local silica sand ore has been investigated using a batch, benchscale mechanical flotation cell. The effects of various operating parameters such as type and concentration of collectors, type of acid, pH, conditioning time, solidinpulp concentration, particle size and temperature have been studied on the hematite removal efficiency by reverse flotation.
With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century''s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
