why slag crushing before industrial application - COPPER Copper production - TU Delft
The copper concentrate is first sent through the smelting furnace to be heated up to 2,300 °F and converted into molten liquid. The heated liquid is poured into a slag-settling furnace. This step produces a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities.Recovery of cobalt, nickel, and copper from slags, using DC …. The most effective means for the recovery of metals …. Molten slag may be fed directly to the 5.6 MVA furnace from a pre-melting …. When treating furnace slag ….

3. Optimized furnace shell design with steam jacket amplifies reaction zone and smelting effect and reduces heat loss; 4. Reduced investment of waste heat exchanger for cooling the off-gas; 5. High metal recovery rate, normally less than 0.3% metal in slag; 6.Copper slag is a by-product of copper production from copper ore. For every ton of copper produced about 2.2 ton of slag is generated. At present, across the world around 33 tonnes of slag is generated while in India three copper producers Sterlite, Birla Copper and Hindustan Copper produce around 6-6.5 tonnes of slag at different sites.
