Abstract:
     There are many kinds of technological process of extracting sulfuric slag to obtain iron concentrate, and the present invention is one technological process comprising milling sulfuric slag, controlled dispersion and floatation. Compared with other technological processes, the present invention has the advantages of high grade of obtained iron concentrate, high yield, etc. For example, the said technological process can extract sulfuric slag with iron content less than 50 % to obtain iron concentrate with iron content over 60 % and in the iron recovering rate over 70 %. The said technological process is simple, uses conventional apparatus and is easy to use in industrial production.
