Nickel is an important strategic metal, which is mainly used for stainless steel production.In the recent years, ferronickel has been used as a substitute for electrolytic nickel for reducing the production cost of stainless steel. Rotary kiln-electric furnace (RKEF) smelting is currently the world-wide mainstreaming process for ferronickel production from nickeliferous laterite ore, in spite of the high power consumption. In this study, aiming to provide some meaningful guidance for ferronickel production of RKEF smelting, reductive roasting followed by smelting process was carried out. The conditions including reducing parameters (roasting temperature and time) and smelting parameters (coke dosage, CaO dosage, melting temperature and time) were ascertained. The metal recovery ratios, as well as Ni, Fe, S and P content of ferronickel were considered. The results showed that a ferronickel containing nearly 15 wt.% Ni was obtained from a nickeliferous laterite with 1.91 wt.% Ni.
