摘要
A method of suppressing dust formation in a particulate mineral material, which particulate mineral material has been dewatered from a suspension of said material, comprising the steps of transferring the suspension of particulate mineral material as a fluid to a deposition area, and in which the suspension is allowed to stand and dewater at the deposition area to form a dewatered particulate mineral material, wherein suppression dust formation of the material is achieved by adding a dust suppressing amount of a polymer to the suspension of the particulate mineral material while it is being transferred as a fluid to the deposition area, wherein the polymer is either a synthetic water-soluble polymer formed from one or more ethylenically unsaturated monomers having an intrinsic viscosity of at least 4 dl/g or a water-soluble polymer that is a natural polymer or semi natural polymer.
