Atmospheric pressure leaching application for the recovery of

Nickel laterite ores may be processed by direct smelting to produce ferronickel, without the concentration stage; however, this is not a commercial practice (Norgate and Jahanshahi, 2010). Atmospheric pressure leaching has been suggested as a method of replacing high-pressure acid leaching, which entails high costs due to expensive materials required for
