process for purifying silica sand - materias primas

While the process described by Coke is highly efficient to remove aluminous substances from silica sand, it relies on the selectivity of the fatty amine collector for the aluminous materials, which selectivity is destroyed completely when the sand particles are coated with even light stains of ferro-aluminous impurities, inasmuch as the fatty amine collector "confuses" the thusly coated silica sand particles with the particles of the silico-aluminates and other aluminum compounds, and tends to float the same together with the silico-aluminates, thereby producing an extremely high loss of silica sand in the froth removed from the flotation process and containing the silico-aluminates
