PRODUCTION METHOD OF SALTS OF BIVALENT AND TRIVALENT IRON WITH SLAG OF METALLURGY OF FERRO-NICKEL OR STEEL INDUSTRY FOR USE IN THE PRODUCTION PROCEDURE OF CEMENT AND ELSEWHERE.

摘要

The slag of metallurgy of ferro-nickel and steel industry is exposed in a suitable reactor with sulphuric acid or hydrochloric acid and solid mixtures of iron salts and/or solutions thereof are produced. he solid mixtures are dried and abraded , they are packed and they are distributed in the market. The solutions are separated from the insoluble part and they are crystallized in the respective salts of iron that after a drying and abrasion they are packed and distributed in teh market. The insoluble part of mostly amorphous silicon is dried, packed and distributed in the market for the production of building materials. Solid mixtures and-or pure salts of iron salts are used in the production procedure of cement, in water and waste treatment as well as in other uses.
