read morerecover of copper and molybdenum from a slag [17]. Selective recovery of copper metal requires an oxygen potential below 10-6 atm. In the case of copper, increasing of oxygen potential must ensure to obtain the metal at around 10-6 atm, but at this level, also iron will largely present as magnetite. Molybdenum metal

The compositional analysis (Table 1) confirms the presence of iron, silicon, zinc, and aluminum as the significant element in the copper slag, and some other elements in lower level of concentrations, such as calcium, magnesium, chromium and copper.This waste is regarded as hazardous materials in many countries due to the presence of heavy metals.
read moreThe copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag…
read moreconcentrate, various mining operations have initiated the recovery of copper from dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag.
read moreThe slag from the furnace is essentially an iron-calcium silicate and some oxides. The copper matte is transferred to a converter where iron sulfide is removed as a copper-rich slag, and finally the copper sulfide ('white metal') is blown with air or air and oxygen to produce blister copper for subsequent fire and electrolytic refining.
