Nickel Laterite Rotary Kiln-Electric Furnace Plant Of The
It is proposed that a single RKEF line comprising one kiln producing 240 t/h of calcine feeding a 120 MW furnace could process 2 million tonnes per year of dry new ore which, for an ore grade of 2% nickel, is equivalent to 36,000 t/y of nickel per line. The plant could also be twinned to double the capacity to 72,000 t/y of nickel.

Agata North Nickel Laterite DSO Project, Mindanao
The Agata nickel processing plant is expected to commence production in 2016 and is expected to have a lifespan of 20 years. The laterite material consisting of limonite and saprolite will be combined with sulphuric acid at the processing plant, and the resultant intermediate nickel product will be either sold as it is or further processed to produce metallic nickel.
