Smelter slag dumps with approximately 16.500.000 tons of slag and 700-1000 tons of daily produced slag in Bor Copper Mine smelting plant, represents a significant economic potential, as well as ...
The flotation process involves adding various chemicals to the copper slag to make it hydrophobic, or water-repellent. This allows the copper to attach to air bubbles, which are then floated to the surface of the flotation cell. Once at the surface, the copper-rich froth is skimmed off and sent to a recovery tank where the copper is separated ...

It has been estimated that for every ton of copper produced, approximately 2.2–2.5 tons of slag is generated as a result of the relatively low grades of copper concentrates now available. 2 There are several copper smelting plants throughout the world, and this has resulted in the production of approximately 40 million tons per year of …
Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 wt% Cu and 35–45 wt% Fe equivalents to those in the copper and iron ores, respectively. Most of the research was focused on the recovery of iron from the …
Mineralogical composition of these slag carried out in this work showed that the most dominant oxide minerals in these slag are fayalite and magnetite phases while the most dominant sulfide minerals is a solid solution of Cu-Fe-S.
