The plant was moved to the new site At the new plant the conventional sintering electric furnace process was replaced with a rotary kiln electric furnace process which is more efficient than the former process and is well suited to large scale production Initially two electric furnaces of 14 MVA and related facilities were com pleted in 1968
laterite ore by pyrometallurgy process has been used as a substitute for electrolytic nickel in recent years [4 5] Rotary kiln electric furnace RKEF smelting is a successful process for disposing nickeliferous laterite ore to produce ferronickel it has the advantages of raw material
Rotary kilns sometimes called calciners or rotary furnaces are used for thermal treatment processes such as calcination sintering pyrolysis and firing as well as for oxidation and treatments can be applied to powders granulates suspensions and green rotary kiln consists of a cylindrical rotating body mounted between stationary material
Rotary kiln electric furnace RKEF technology accounts for 95 pct of the lateritic nickel ore processing Coal is commonly used as fuel and reducing agent in the rotary kiln to produce solid reduction product which is then melted in the electric furnace The use of coal in the process leads to the emission of approximately 70 tons of CO2 for every 1 ton of nickel in
