Abstract
A method and composition for control of in-transit and residual dust from coal or coke is provided. The method involves spraying the coal or coke with fluid, preferably water, containing an additive comprised of approximately 90-99% by weight of lignosulfonate and 1-10% by weight of a polyacrylate, a polyvinylalcohol, or a polyacrylamide. Sufficient fluid should be used to coat the coal or coke. The amount of additive necessary to prevent dusting will vary according to the conditions to which the coke or coal will be subjected.
