Dust suppression in iron ore processing plants SpringerLink

Nov 01, 2005  To effectively suppress dust, the material must wet well and must remain wet. Surfactants, hygroscopic materials and binders are additives that address at least one of these concerns. Evaluating the wetting behavior of the iron ore revealed that the pellets were highly hydrophilic (contact angles less than 30°).
