ABSTRACT:
Bulk coal, i.e. coal in coal cars, in piles, in bins, in ships, or in any other place where coal fines tend to become entrained in ambient air, is protectively coated to prevent the loss of coal fines. The coal is first coated with a wetting agent and then coated with an emulsion of crude coal tar in water containing a cationic emulsifying agent.
