CARRIAGE OF NICKEL ORE AND IRON ORE FINES : Detailed Bulletin

Nickel ore is mined largely in Indonesia and the Philippines. Very little processing takes place when the ore is mined: it is usually dug up, sorted for size, stored in stockpiles and then shipped. Different mining methods are used in different areas, which can lead to variations in the physical consistency and moisture content of the cargo.

Nickel occurs occasionally free in nature but is mainly found in ores. Its chief ores are pentlandite and pyrrhotite (nickel-iron sulfides), garnierite (nickel-magnesium silicate), millerite (nickel sulfide) and niccolite (nickel arsenic). Nickel is taken from its ores by roasting and reduction processes which produce a metal of over 75% purity.
