Nov 01, 2020#0183;#32;Table 2, Table 3 revealed that zinc and copper were mainly present in the forms of zinc oxide and zinc silicate and cuprous oxide and cupric oxide, respectively. The smelting slag sample was ground, mixed, dried, and sieved to obtain 6575 m particles for the leaching experiments. Ammonium chloride with a concentration of % and stronger ammonia water with a concentration of 28% were
The slurry was stirred by magnetic stirrer. A schematic flow diagram of the leaching of copper from copper slag is shown in Figure 1. The optimum digestion temperature is 250oC, at which a high recovery of copper from copper slag is achieved. Figure 7. Copper
A magnetic product containing about % iron was obtained from the magnetic separation under a magnetic field strength of 100 mT. Large amounts of copper slag containing about 40 wt% iron is generated during the process of producing copper. Recovery of iron from the copper slag is very essential not only for recycling the valuable metals
Copper mainly dwells in the slag in the form of bornite, chalcocite, chalcopyrite, and metallic copper. The rest are iron minerals like magnetic iron ore, metallic iron and gangue like fayalite, hedenbergite and amorphous phase matter. Such slag can be concentrated by separation and enrichment to obtain copper
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
By using DR followed by a magnetic separation process for iron recovery from copper slag, Yang obtained iron powder of % iron content with an iron recovery rate of %, and Wang obtained iron powder of % iron content with an iron recovery rate of %. Both of their tests have achieved good results.
Jan 01, 2007#0183;#32;Thus, the participation of electrolysis in copper recovery is decreasing from 25% to 5% with the decreasing concentration of dissolved cuprous oxide. 6. Effect of crossed electric and magnetic fields on the rate of slag reduction
Iron Recovery from Copper Slag Through A magnetic product containing about % iron was obtained from the magnetic separation under a magnetic field strength of 100 mT. Large amounts of copper slag containing about 40 wt% iron is generated during the process of producing copper. Recovery of iron from the copper slag is very essential
Recovery of Iron from Copper Slag Using CoalBased Direct Reduction: Reduction Characteristics and Kinetics. Minerals 2020, 10 Was the copper slag used in this study slow cooled or quenched? If magnetic separation is a key difference in iron recovery than an entire section in methods and an entire section in results should be added.

Oct 05, 2020#0183;#32;Smelter slag, a byproduct of metallurgical processes, was made and dumped for over 100 years of ore exploitation in Bor Copper Mine. Smelter slag dumps with approximately tons of slag
LATEST RESULTS OF THE SLAG CLEANING REACTOR FOR COPPER RECOVERY 199 The slag velocity is similar. The results of CFD modelling (Figure 3 and 4) for a large furnace show very high slag velocities (up to m/s) below the electrode at low magnetic field values ( tesla). The second part of the channel furnace has a
The new process for slag cleaning includes a rectangular DC reactor with an additional magnetic field generated by electromagnets for improved metal/matte recovery. The slag into the reactor is
About million tonnes of copper smelter slag are available in K#252;re, northern part of Turkey. This slag contains large amounts of metallic values such as copper and cobalt. A representative slag sample containing % Cu, % Co and % Fe was used in the experimental studies.
