Recovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. 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 ...
متن کاملThe effective parameters on thermal recovery and reduction of iron oxides in EAF slag
Steelmaking slag of Mobarakeh Steel Company (MSC) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. On the other hand, EAF slag in this company is almost free of zinc because of using more than 90 percent DRI in the charge. Therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. In...
متن کاملChromium and phosphorous recovery from polluted water by hydrothermal mineralization
Detoxification of polluted water containing chromium and phosphorous and its resource recovery were investigated by hydrothermal mineralization using Ca(OH)2 or CaCl2 mineralizers. Under the optimum treatment condition for removing chromic acid (at 473 K, for 2 h using CaCl2 mineralizer in an in situ sampling-type autoclave), CrO4 was recovered as CaCrO4 and the concentration in the treated-wat...
متن کاملElectrochemically Enhanced Reduction of Iron Oxide from Slag
An experimental study was performed to measure the rate of reduction of iron oxide from calcia-silica-alumina slag by carbon in iron, and to determine whether the reaction rate can be increased by electrochemical means. It is shown that the reaction rate depends on both the ferric-ferrous cation ratio, and on the total amount of iron in the slag. It was observed that ferric cations are reduced ...
متن کاملRecovery of Vanadium from Esfahan Steel Company Steel Slag; Optimizing of Roasting and Leaching Parameters
In this Study, vanadium recovery from the steelmaking converter slag was studied. Salt roasting-basic leaching is the process which was applied to separate and extract vanadium from steel making slag. Ground slag was roasted after mixing with determined quantities of sodium carbonate. The effect of time and temperature of roasting and sodium carbonate content were studied. The optimum temperatu...
