Processing of Nickel Laterite Ores on the Rise In the Caron process, the ore is first dried and then reduced, similar to the RKEF method. However, once the ore has been reduced, it is then leached via ammonia to extract the metal components (nickel is often accompanied by cobalt and iron). The extracted metals can then be purified/refined.
Nickel: smelting, producing-Metalpedia Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite.
