The development project comprises four rotary kiln electric furnace RKEF lines and a 380 megawatt power station currently under construction on Halmahera Island in the North Maluku province.
An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in the rotary kiln-electric furnace RKEF for the smelting of ferronickel
Oct 25, 2016 An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in the rotary kiln-electric furnace RKEF for the smelting of ferronickel alloy. One of the measures is to recover the waste heat of exhaust gas from the rotary kiln for preheating and dehydrating the wet laterite ores in the rotary dryer.
Rotary Kiln - Electric Furnace RKEF process is a pyrometallurgical technique to extract nickel from laterite ores. It is essentially a two-step process where the ore is first calcined in a rotary kiln and then smelted in an electric furnace.
May 01, 1987 Hyuga Smelting Co., established by Sumitomo Metal Mining Co., started the production of ferro-nickel by the sintering-electric furnace process in September 1956. In accordance with the rapid increase in market demands, the company made a steady growth, expanding the production capacity from 30 to 200 tons of nickel per month.
