Evolution of ferronickel particles during the reduction of
The method of producing ferronickel at low temperature (1250–1400°C) has been applied since the 1950s at Nippon Yakin Kogyo, Oheyama Works, Japan. Limestone was used as an additive to adjust the slag composition for lowering the slag melting point. The ferronickel product was recovered by means of a magnetic separator from semi …

Recent Progress in Hydrometallurgical Processing of Nickel Lateritic Ore
Lateritic ore contributes to 70% of total nickel resources. However, due to its low grades, and comparatively higher impurity constituents, it requires specific preprocessing steps prior to utilization. The present article reviews the insight into the available hydrometallurgical approaches for treating laterite ores and the separation of ...

Of the three, nickel is the least magnetic. When all three ferromagnetic metals are alloyed together in combination with some additional elements, an unusually strong magnet, called an alnico magnet, is created. This alloy also conducts heat and electricity fairly well. Alnico magnets are the only magnets that have useful magnetism when heated ...
