    copper recovery from slag in india - ckequestrian

    Recovery of cobalt, nickel, and copper from slags, using,Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DCarc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining the maximum possible quantity of iron as oxide in the slag.Characterization and recovery of copper values from,,The recovery of copper values from an Indian smelter slag that contains 1.53% Cu,,These results are compared with obtained copper recovery of pure copper slag.Copper Recovery from Reverberatory Slag,White Pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. Among them: White Pine concentrates yield extremely high matte grades (65+% Cu) and viscous slags. The viscous slags hinder matte settling causing matte “prill” entrapment in the slag. White Pine’s total refined copper output is accomplished through fire refining,

    01-05-2010· This inert slag can also be used for land filling, for making of road and in construction works like embankment for rivers, etc., Converter slag (0.36 kg/kg of copper) produced from SWIL and slag (1.6 kg/kg of copper) from Birla copper (Sharma, 1998a, Sharma, 1998b) is granulated and sold out to the construction companies for road making, as abrasives for shot blasting media.Recovery of metal values from copper slag and reuse of,,Copper slag was characterized and processed. The pyro-metallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product which can be a feed material for steel making.A Study on the Recovery of Iron from Copper Slag with,,Since the copper smelting slag contains high content of Fe, Cu and valuable metals, interest in recycling it is increasing. The high Fe content in the copper smelting slag can be used as a high-value element that can replace the foundry pig iron. Therefore, this study was intended to recover Fe-Cu alloy from the copper smelting slag

    Recovery of cobalt, nickel, and copper from slags, using,

    Copper sulphide and copper metal (with its inherent cobalt content), because of their higher densities and immiscibility with the slag, settle from the molten slag into the metal bath. Improving recoveries via this mechanism would involve decreasing the viscosity of the slag (by increased temperature or flux additions), and / or increasing the settling time to allow smaller droplets to fall.(PDF) Recovery of metal values from copper slags by,,The recovery of copper values from an Indian smelter slag that contains 1.53% Cu, 39.8% Fe and 34.65% SiO(2) was the focus of the present study.
