Abstract

PURPOSE: To perform the antipollution treatment for the steel making dust with high efficiency by a procedure in which the steel making dust is kneaded with a soluble sulfide and an appropriate amount of water, molded into a desired shape as needed, and then cured by heating.
CONSTITUTION: The steel making dust is mixed with the appropriate amount of the soluble sulfide and water in an amount enough not to make the mixture a slurry, kneaded and molded into a desired shape as needed, and then cured by heating to a temperature not higher than 400°C. Thus, the elution of harmful metal components from the steel making dust can be effectively suppressed.
