These are carried out in large rotary-kiln furnaces. Dryers 50 metres long and 5.5 metres in diameter are common, while reduction kilns 5 to 6 metres in diameter and more than 100 metres long are required to handle the large tonnages of ore and to provide the necessary retention time. Next, it is necessary to reduce the oxide to nickel metal.
