Apr 01, 2021· Globally a large volume of copper slag is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [].Table 1 illustrates the magnitude of slag produced in different areas in the world and Botswana ...
The recovery of cobalt and copper from waste slag was studied in a plasma DC-arc furnace in reducing conditions. Three fluxes, CaO, CaF 2, and TiO, were investigated for their influence on selective recovery of cobalt into an iron-rich alloy. A further investigation on the influence of furnace power on the reduction of slag to recover

The 20 Mt reverberatory furnace slag dump at Nkana in Zambia contains a substantial quantity of cobalt. A 40 MW DC arc furnace has been built at Chambishi for the purpose of recovering cobalt from the slag. The technology was jointly developed by Mintek and Anglovaal Mining Ltd (Avmin), and the furnace was designed by Bateman Titaco. Testwork at the 150i?½250 kW scale was conducted at AVRL ...
In the present work, the effects of amount of coke, reduction temperature and furnace types on copper slag smelting in a dc arc furnace were studied. Optimum coke amount was found to be 10% of the slag weight in an open-top furnace for a 1 hour reduction time in the temperature between 1703 K and 1753 K. Similar conditions in a closed-top furnace resulted in higher cobalt and copper contents ...

Cobalt can be recovered from a variety of slags by treatment with a carbonaceous reducing agent in a direct-current arc furnace at around 1,500°C. The principal materials suitable for treatment using this technology are primary smelter slags, which typically originate from the processing of sulfide concentrates. The technology has been tested using copper, nickel-copper, and lead smelting slags.
