  • The method to produce ferronickel at lower temperature (1250-1400℃) was applied since 1950s at Nippon Yakin Oheyama, Japan. Limestone was used as an additive to adjust the slag composition for lowering slag melting point. The ferronickel product was recovered by means of magnetic separator from semi-molten slag and metal after water quenching. In order to increase the efficiency of magnetic separation, bigger particle size of ferronickel is desired. Therefore, in this study, the influences of CaO, CaF2 and H3BO3 additives on the evolution of ferronickel particle at temperature ≤ 1250℃ were investigated. The experiments were conducted at 900-1250℃ with the addition of CaO, CaF2, and H3BO3. The reduction processes were carried out in a horizontal tube furnace for 2 h under argon atmosphere. The results showed that at 1250℃ with the CaO addition of 10% of the ore weight, the size of ferronickel particles of 20 μm was obtained. The ferronickel particle size can be increased to 165 μm by adding 10% CaO and 10% CaF2. The addition of boric acid further increased the ferronickel particle size to 376 μm as shown by the experiments with the addition of 10% CaO, 10% CaF2 and 10% H3BO3.

Abstract: The method to produce ferronickel at lower temperature (1250-1400℃) was applied since 1950s at Nippon Yakin Oheyama, Japan. Limestone was used as an additive to adjust the slag composition for lowering slag melting point. The ferronickel product was recovered by means of magnetic separator from semi-molten slag and metal after water quenching. In order to increase the efficiency of magnetic separation, bigger particle size of ferronickel is desired. Therefore, in this study, the influences of CaO, CaF2 and H3BO3 additives on the evolution of ferronickel particle at temperature ≤ 1250℃ were investigated. The experiments were conducted at 900-1250℃ with the addition of CaO, CaF2, and H3BO3. The reduction processes were carried out in a horizontal tube furnace for 2 h under argon atmosphere. The results showed that at 1250℃ with the CaO addition of 10% of the ore weight, the size of ferronickel particles of 20 μm was obtained. The ferronickel particle size can be increased to 165 μm by adding 10% CaO and 10% CaF2. The addition of boric acid further increased the ferronickel particle size to 376 μm as shown by the experiments with the addition of 10% CaO, 10% CaF2 and 10% H3BO3.
