Chromite ore deposits were discovered in Kemi in 1959. Mine operations and ferrochrome production began in 1968. The mine was expanded in 1985 with the launch of Tornio's second ferrochrome smelting furnace and in 2013 with the opening of a third ferrochrome smelting furnace. Kemi mine production moved underground in 2003.

Chromite is an iron chromium oxide mineral (FeCr2O4), which is a source of commercial importance. It contains 68% of chromic oxide (Cr2O3), wherein the proportions of Fe2+, Fe3+, Mg2+, Cr3+ and Al3+ may differ significantly. Chromite produces Ferrochrome, which plays a key role in the steel industry.
Africa was the leading chromite ore producer. Increased labor costs, increased costs for electricity, an unreliable supply of electricity, temporary mine closures related to the COVID-19 pandemic, and challenges related to deep level mining could affect production in South Africa in 2020. China was the leading chromium-consuming country.
