Chrome Mining - BAUBA

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.

Tata Steel Mining Ltd aims high to establish itself as a

Formerly known as TS Alloy Limited, the wholly owned subsidiary of the group, is at present engaged in the mining of chrome ore and the production of ferro chrome. Apart from having ferrochrome plants at Athagarh and Gopalpur in Odisha, the company has three chromite mines, namely Sukinda, Kamarda and Saruabil, in Jajpur district of the state. Samancor’s operations are centred on reserves held in the Bushveld layered intrusive complex, which contains approximately 70% of the world’s economic chrome ore reserves in the Lower Group (LG) 6 and Middle Group (MG) 1 seams. LG6 has a Cr2O3 content of 43-47% and a Cr:Fe ratio of 1.6:1, while MG1 averages 42% Cr2O3 and a Cr:Fe ratio of 1.5:1. LG6 is typically 1.1m thick and MG1 1.4m, both dipping gently. At end-June 2002, Samancor’s proven reserves totalled 16.6Mt grading 42.4% Cr2O3 with probable reserves of 23.4Mt. Total resources are estimated to be sufficient for 200 years of mining at current rates. See full list on mining-technology.com Samancor has two mining centres: Eastern Chrome Mines (ECM) in the Steelport area of Mpumalanga Province and Western Chrome Mines (WCM) near Rustenberg and Brits in Northwest Province. Both units now comprise five underground mining areas, each with a hoisting shaft, while WCM also includes an open-cut mine. Overall capacity is approximately 5.8Mtpa of run-of-mine ore. Underground, Samancor relies mainly on room-and-pillar mining, typically with low-angle adits connecting to a horizontal access level. Thin seams limit the scope for mechanisation and blasting relies on drilling with handheld pneumatic jackleg units. The ore is mined either up-dip or down-dip in rooms approximately 20m-wide, with the roof supported by ore pillars. Scrapers haul chromite to ore passes that load trains on the haulage level. The trains load a conveyor in the hoisting adit. The dimensions in the Waterkloof/Millsell mining block have allowed WCM to replace scrapers with load-haul-dump machines. The open cu See full list on mining-technology.com Samancor’s concentrators – three for ECM and three plus a fluidised bed dryer for WCM – are individually configured to treat specific feed and yield a particular product range. Bushveld chromite is conveniently milled to recover a fine concentrate by gravity and elutriation techniques. However, ferrochrome furnaces need a porous charge so lumpy ore and chips must also be recovered by dense medium separation to mix with the fines. The fines may be agglomerated at the smelters, either by briquetting or using the Outokumpu pelletisation and preheating system, to reduce the amount of lumpy ore and chip required. Further gravity separation and elutriation steps yield the specific grain sizes and reduced levels of impurities, such as silica, required for the chemical and foundry sand markets. Samancor currently operates three flexible smelting systems with capacity in excess of 1Mt/y of ferrochrome at three sites. The mines also feature six Submerged Arc Furnaces (SAF), a metal recovery p See full list on mining-technology.com In 2000, Samancor Chrome produced 3.7Mt of chromite and 1.06Mt of ferrochrome. Output fell in the depressed market of the following two years but recovered to 1.02Mt of ferrochrome in 2003. Total saleable production in the year to June 2004 was 1.026Mt, and that in the year to June 2005, 954,000t. Approximately 0.5Mtpa of chromite is exported, mainly as chemical-grade or foundry sand.

The Mining of Chrome in South Africa This report focuses on the chrome ore mining sector in South Africa. The country holds 72% of global chromite resources, which includes more than 41% of the world’s reserves, and during 2014 the industry produced 15Mt of chromite, exporting 7Mt valued at US$1.1bn.

Boldman Mining

The Company’s priority is establishing itself as an international, top-tier of coal, gold and chrome producer through the advancement of its strong and details pre-feasibility studies. The deposit, located in Guruve, Zimbabwe has the potential to become one of the world’s largest and lowest-cost primary chrome mines.
