Initially the slag contained 2 wt% Ni and 1 wt% Cu, Co and P each, added as oxides, and at PO2 = 10⁻⁷ atm, these metals were only present in the slag with no metal alloy formed.
Copper slag was reacted with metallurgical coke for comparison and the products were analyzed with EPMA and LA-ICPMS. The results revealed that reduction rapidly progresses to the formation of metal alloy within 10 min. Valuable metals like copper, nickel and arsenic were the first to be reduced to the metal phase.

Studies were carried out at R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome (ferrochrome with 50–60% chromium) plant, Bamnipal. The studies showed that in the case of the charge chrome plant, crushing of mixed metal and slag to below 10 mm followed by jigging of the −10+1 mm …
The recovery of metals from copper slag using biochar was investigated at three different temperatures from 1250 to 1350 °C. Each experiment was carried out for 60 min. The samples were molten at the reduction temperatures and solidified after quenching. SEM micrographs of polished sections show that metal alloy was generated in each temperature.
Slag is a by-product of iron making in blast furnace steel mills. For a cubic meter of molten metal 280 to 340 kg of milk is produced in modern blast furnaces. In Algeria the annual production of milk is estimated at 500,000 tones finding only a few applications [10,11].
Unlike iron slag and steel slag, the study on metal recovery and utilization of stainless steel slag is just in its infancy (Shen and Forssberg, 2002, Kortbaoui et al., 1993). It was reported that magnetic separation or gravity separation methods had been used for recovery of Ni and Cr from stainless steel slag in some commercial processes ...

Copper slag (CS) is a solid waste produced during copper smelting, mainly containing 30–––40 % Fe, 1.74–4.48 % Zn, and other trace amount metal elements (Shibayama et al., 2010, Gümüşsoy and Başyi̇ği̇t, M., Uzun Kart, E.,, 2023).It is reported that China currently produces over 60 million tons of CS annually and possesses a stockpile of 130 million tons of …
Metal recovery from this slag was examined using three methods employed for the fumer slag study: 1) holding at temperature to allow the divalent iron to reduce the metal ions into the gas phase; 2) equilibration with a copper "getter" and 3) electro reduction into a liquid copper cathode using a graphite anode. ...
