Neither separation is very efficient as presently practiced. The furnace slag itself contains recoverable metallic iron, but its separation requires that the slag be crushed and magnetically separated, an inefficient, labor-intensive process. Finally, the oxygen furnace produces a fine dust that must be separated and collected.

A review on lead slag generation, characteristics, and

Jul 01, 2019 Wang et al. (2017) studied the recovery of iron, lead, and zinc from lead slag by means of coal-based direct reduction. After the direct reduction, fayalite and magnetite in the lead slag were transformed into metallic iron. An iron grade of 93.73% was obtained and a recovery rate of 80.32% was achieved through magnetic separation.

Feb 20, 2021 Through magnetic separation, the metallic iron in leaching residue is mainly enriched in the concentrate (Fig. 7b), and the impurities are discarded into the tailing (Fig. 7c). The independent silica particles are detected in the tailing, thereby confirming the stability of natural quartz under these leaching conditions.
