The testing results showed that the optimal reduction conditions are 1320℃ for 120 min and the proportional mass fractions of activated carbon powder and the additive A are 3% and 5%, respectively. The additive A accelerates the aggregation of metallic grains so as to make the enriched metallic grains easier for magnetic separation. The mass fraction of maximum nickel in ferronickel alloy and nickel recovery in the laterite-nickel ore are 8.31% and 95.44%, respectively. Metallic nickel is thus enriched.
