Iron Ore Concentrate Surfactants

Surfactants amp mine dust control amp effect on flotation. dust measurements in mines clearly indicated that the major mineral dust exposure is due to loading and transport of the ore from the mining areas. one approach to the solution of this dust problem is the application of water sprays to reduce dust dispersion.
