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 .
Studies on the direct reduction of carbon-bearing pellets made from discarded copper slag have been conducted in this paper. They include the influences of reduction coal content, limestone content, industrial sodium carbonate content, reduction temperature, reduction time and layers of carbon-bearing pellets on reduction effect. Finally, the optimum conditions have been obtained.
Copper Recovery is a manufacturer of wire and cable recycling equipment, offering sales and service worldwide. We also act as agent or representative for some of the finest European manufacturers of recycling machinery. Most recently, we infused our knowledge and know-how gained over the last 18 years of cable recycling, combined it with a ...
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 .
Smelter slag, a by-product of metallurgical processes, was made and dumped for over 100 years of ore exploitation in Bor Copper Mine. Smelter slag dumps with approximately 16.500.000 tons of slag ...

Slag Deepfield Copper Electromagnet Few materials are as damaging to magnets and equipment as slag, but the extra-heavy-duty structural design of the Slag Deepfield Copper Electromagnet (SDC) is built to take it. Whether it's ultra-abrasive scrap, slabs, billets, drop balls, or slag scrap, this is the magnet that can do it all. The copper-wound version.
A magnetic product containing about 57.9wt% 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 ...
