The reverberatory furnace slag that has been discarded in the vicinity of the Bor Copper Smelter, Serbia, is currently processed by flotation at the nearby Bor Copper Concentrator. The copper recovery was rather low (about 40%) mainly due to the presence of oxide copper and insufficient mineral liberation. In our previous work, we
Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were 63.4% and 48.6%, respectively, when leaching the slag with 3 M H2O2, after 120 minutes of reaction at… View via Publisher
Waste copper slag is a typical hazardous solid waste containing a variety of valuable elements and has not been effectively disposed of so far. In this paper, a stepwise extraction process was proposed to recover valuable elements (copper, iron, lead and zinc) from waste copper slag. The specific procedures are as follows: (1) A flotation process was …
Recovery of copper from copper slag and copper slag flotation tailings 75by oxidative leaching Table 1. Chemical compositions of the copper smelter slag and the slag flotation …
production is produced by smelting flotation copper sulphide concentrates in reverberatory furnaces, followed by oxidation of matte to blister copper in a converter. The slag from the converter contains too much copper to be sent to landfill and is returned to the reverberatory furnace to recover most of the copper.
In the traditional smelter, copper is recovered from the converter slag by returning the molten material back to the reverberatory furnace. There, the magnetite in the converter slag is...
Sarrafi et al. (2004) found that 72% copper recovery could be achieved using mercaptobenzothiazole (MBT) as collector from a reverbaratory smelter slag containing a total …
Copper smelting slag is produced from copper pyrometallurgy (both smelting and converting stages), usually grading at 0.3-3%. The slag may also contains lead & zinc minerals like galena, sphalerite. Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper.
So far, many studies have been carried out on the recovery of copper from slag, in which the methods used are leaching, flotation, direct reduction and bio-leaching [3,4,5,6]. …
Sibanda et al. (2020) indicated that copper recovery from CS can be enhanced through a thorough understanding of the mineralogy and liberation profile of the slag, together with an optimization on the flotation reagents. Fan, Li, Wei, Li, and Sun (2017) concluded that three factors affect CS flotation: particle fineness, collector type, and pH.
