Copper slag is a by-product obtained during smelting and refining of copper. Copper smelting slag typically contains about 1 wt. copper and 40 wt. iron depending upon the initial ore quality and the furnace type. Main components of copper slag are iron oxide and silica. These exist in copper slag mainly in the form of fayalite 2FeO SiO2.
A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag in ...

of slagpyritecopper concentrate and the effect of the added iron powder to leaching on the metals dissolution were investigated. Under optimum conditions, 99.6 of copper and 98.4 of cobalt were extracted in roasting at high temperatures in a closed medium
materials from copper slag. Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research. Metals, commercial compounds, alloys and different forms of iron oxides for steel industry are proposed products.
reduction of metallic iron was evident when copper and cobalt levels in the slag fell below a lower value 18 . This diluted the copper and cobalt levels in the matte and changed the properties of slag and eventually reduced the recovery of copper and cobalt. Y. Li et al. JMM 54 1 B 2018 73 -
Copper slag can also be used as a building material, formed into blocks. Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools. In general, the spent copper slag is suitable to be used as a fill material for land reclamation.
The process involves the selective carbothermic reduction of the oxides of cobalt, nickel, and copper, while retaining the maximum possible quantity of iron as oxide in the slag. Early pilot-plant testwork 1 at Mintek demonstrated recoveries of 98 for nickel and over
