Abstract
Methods including placing particles that are substantially dry in a hopper; conveying the particles from the hopper via a conveyance to an open-air gap; adding a fluid to the particles in the hopper, the particles in the conveyance, or both, thereby reducing an amount of a dust produced at the open-air gap. The particles may be sand, silica, gravel, bauxite, ceramic materials, glass materials, polymer materials, polytetrafluoroethylene materials, nut shell pieces, cured resinous particulates comprising nut shell pieces, seed shell pieces, cured resinous particulates comprising seed shell pieces, fruit pit pieces, cured resinous particulates comprising fruit pit pieces, wood, composite particulates, and combinations thereof.
