May 10, 2017 Lead, zinc, and iron were recovered from jarosite residues using direct reduction followed by magnetic separation. The influence of the coal dosage, reduction temperature, and reduction time on the volatilization rates of lead and zinc and the metallization rate of iron were investigated. The results show that the volatilization rates of lead and zinc were 96.97% and 99.89%,

to separate Pb, Zn, and Fe from lead slag. Lead slag was mixed with coal and additive and treated in a laboratory tube furnace. In the process of direct reduction, Pb and Zn compounds were reduced to ele-mentary substances and entered into flue gas as dust. Fe was reduced to metallic iron and separated from roasted slag by magnetic separation.

(PDF) Recovery of Iron and Zinc from Blast Furnace Dust

For the comprehensive recovery of copper, zinc, silver and iron from the zinc volatile kiln slag in Xining, exploratory experiments were conducted by adopting single flotation, magnetic separation and combined process of magnetic separation and flotation. The results showed that the above process cannot effectively recover copper, zinc and silver from the ore.

The finer fractions contain so-called magnetic slag, these are nuggets consisting of mineral and metal. Magnetic slag can be best separated with a 1,800 or 3,000 gauss head roller magnet. Using the band speed and the position of the separation bulkhead, the grade of

6 Steel Industry | Separation Technologies for the

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.
