Abstract
A method of making a pneumatically injectable additive for an Electric Arc Furnace, the method comprising screening a waste material comprising oily millscale in water to form uniform particles, and then mixing those particles with carbon and lime; and storing the mixture in air permeable bags in a dry atmosphere until the mixture has chemically cured to form the injectable particles.
