Abstract

PURPOSE: To precipitate carbonates of alkaline metals and reuse them for refining, by grinding slag obtd. by refining of fused iron alloy, dissolving it in water the addition of a substance having oxidizing ability, removing impurities such as P, Si, and S, and concentrating the residual soln. with adding CO2.
