摘要
A method is disclosed for obtaining useful products from cement kiln waste dust. The dust is collected and added to an electric arc furnace where it is melted. The temperatures required to melt the dust are sufficiently high that alkali sulfates present in the dust are volatilized, leaving a melt which has a composition acceptable for the production of cement clinker. The volatilized components are collected to form a second useful product; i.e., a potassium rich material suitable for the production of potassium bearing chemicals, such as fertilizers.
