Copper Mining and Processing: Processing Copper Ores

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.

Copper Production: How Is Copper Made? - ThoughtCo

Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

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

Nickel-copper converter slag 'A'- 100 kVA and 200 kVA. Using converter slag from a nickel-copper plant, tests were carried out, in 1990, on a 100 kVA furnace (operated at 30 kW) and on a 200 kVA furnace (operated at 85 kW), at low additions of reductant (in order to minimize the reduction of iron).

Recovery of iron from copper flash smelting slags: Mineral

Copper slag contains iron in the range of 42–45%, which can be recovered and recycled along with the contained copper to obtain an iron–copper alloy and a final slag rich in oxides. Therefore, the present work shows the experimental results of the reduction of a flash smelting slag using coke as reductant up to 150% of the stoichiometric

UG-Mat Nonferrous Slags | Recycled Materials Resource Center

Air-cooled copper slag has a black color and glassy appearance. As a general rule, the specific gravity will vary with iron content, from a low of 2.8 to as high as 3.8. (15) The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption of the material is typically very low (0.13 percent).

dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption.
