Laterite Nickel Magnetic Properties

Nickel consists of two types of common ores, sulfides and laterite ores. Laterite nickel ore, which comprises 73% of the world's proven nickel reserves is the dominant source of nickel. However, only 42% of the world's production of nickel comes from laterite nickel ore [1], [2]. Ferronickel processing

Nickel-bearing lateritic ores, with average nickel content of 1–1.6%, are formed by tropical and sub-tropical surface weathering. Table 3 summarises these and other types of nickel deposit. Laterites currently account for around 70 per cent of nickel contained in land-based deposits but contribute only 40 per cent of world production.
