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.
