Abstract
A method of treating a material having a plurality of fines of a dusting material to prevent emanation of dust from the dusting material is described. An aqueous solution comprising a mixture of soluble non-ionic cellulose ether, a plasticizer, and a surfactant is provided. The aqueous solution is applied to a dusting material having a plurality of fines. The dusting material is transferred during the applying step from a first location to a second location as the aqueous solution is applied to the material having a plurality of fines. The dusting material is mixed with the aqueous solution to coat the material having a plurality of fines with the aqueous solution. The treated dusting material is accumulated into a mass of the material subsequent to the applying step wherein the aqueous solution is substantially evenly distributed throughout an interior portion of the mass of the treated dusting material.
