] prepared the Fe-Ni particle through carbothermic reduction of a limonitic laterite ore. Hydrated ore such as nickel laterite ore (NLO) is difficult to utilize for its low iron grade and high silica content...] examined the reduction of limonitic nickel laterite to produce Fe-Ni alloy. First, the optimum nickel laterite sinter was investigated through sinter pot test. Then, the nickel laterite sinter was reduced......
