THE CHROME-ORE OPERATION. Bauba diversified its business into low-cost, cash-generative, mining operations in 2015 with the Company acquiring 60% of the beneficial rights to the Moeijelijk Chrome Mine. Moeijelijk is situated on the Eastern Limb of the Bushveld Igneous Complex, with LG6A/6 and LG7 chrome ore-bearing reefs.

Stratiform, Podiform, and Beach Sands. Small amounts of chromite are found in many types of rock. However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the ...

Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs.

Chromite mining has not been systematic but random and totally disorganised. It is mined by both open pit and underground methods. In Muslimbagh, Ras Koh Range and Wad areas, chromite is mostly ...

Because surface mining typically is less expensive than underground mining, it is preferred, but not always possible. Like mining, beneficiation (processing, crushing, separating, smelting, refining, etc.) for chromite depends on the characteristics of the ore deposit and on the mining methods used.

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.

Underground mining is used to recover ores that are deeper into Earth's surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached – from above, below, or sideways – depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.

With PGM mining operations being brought back on-line, fresh by-product chromite concentrates from the UG2 reef will start to resurface. UG2 chromite supply experienced double-digit growth in 2019 and, together with a weaker downstream market, has underpinned low prices for chromite ores and concentrates.
