Abstract: Ferronickel alloy was prepared by magnetic separation and smelting after carbon reduction. The effects of the additive dosage, reduction temperature and time on the enrichment of ferronickel alloy were investigated. Under the conditions of additive dosage of 5%, carbon addition of 3%, reduction temperature of 1320°C and reduction time of 120 min, the contents of Ni and Fe in the magnetic product are 8.31% and 71.5%, and the yields of Ni and Fe are 95.44% and 99.84%, respectively. After smelting, ferronickel alloy with Ni and Fe content of 10.11% and 83.75% was obtained. The analysis of the enriching processes with and without additive show that the home-made additive accelerated and promoted the growth of ferronickel alloy.
