Patent abstract
A long term dust free proppant comprising a mass of free flowing particles, where the particles are coated with a dust suppression solution containing 90 to 99.5 percent by weight water, 0.05 to 3.0 percent by weight a soluble polymer and an added, small amount of a surfactant. The mass has a very low dosage of the solution so the mass has a moisture content of less than 0.30 percent by weight. Preferably the solution is applied to the particles by an air mist jet.
