Abstract
The surfaces of solid fuel particles, in a solid fuel particle slurry in water, are oxidized by exposure to the action of an oxidizing agent, representatively potassium permanganate, to alter the characteristics thereof and permit the employment of reduced amounts of surface-active agent for purposes of attaining desired characteristics of the slurry, which slurry also comprises a part of the invention as disclosed.
