Up to 80 pct of the manganese and. 50 pct of the iron could be extracted from a silicon steel slag that had been pretreated in hydrogen at. 7000 C. Two 4-h.

Recovery of value metals from copper smelter slag by ammonium .

Jan 6, 2018 . Full-text (PDF) | Processing possibility of copper smelter slag produced by Balkhash copper plant (Kazakhstan) was investigated. The effect of temperature and treatment duration on the metal recovery to water-soluble form was studied. A technique of copper, zinc, and iron recovery from the slag of.

Recovery of cobalt, nickel, and copper from slags, using DC-arc .

Processes have previously been described in which carbothermic reduction has been carried out in electric furnaces (1-3). The aim of a slag cleaning process is to maximize the recovery of valuable metals (such as Co, Ni, and Cu) in an alloy with the lowest possible iron content. The amount of metallic iron produced should.
