Roasting Of Copper And Nickel Ore And Ore Concentrates

Separation of the bulk concentrate into a nickel concentrate and a copper concentrate is usually performed when the CuNi mass ratio of the bulk concentrate is greater than 0.3. These concentrates are then dried smelted and refined in separate copper and nickel smelters and refineries. This is discussed in the next chapter.

    Copper Smelting Chemistry Tutorial

    A typical copper ore contains between 0.5 and 2.0 copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores usually higher grade ores by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.

    Processing Of Nickel Laterite Ores On The Rise

    Traditionally nickel has been processed from sulfide ores in an approach similar to copper processing in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle however processing of lateritic nickel ores is becoming of greater necessity with many recogniing nickel laterite ores as the future of the
