17 USGS records of mining mines in Kenya. Gold, Manganese, Rare Earth Elements (REE), Thorium, and Chromium mines located in Kenya.
hromite is the single commercially viable ore of chromium (Cr) which is chemically known as iron chromium oxide (FeCr 2 O 4). The properties of chromium that make it most versatile and indispensable are its resistance to corrosion, oxidation, wear & galling and enhancement of hardenability. Chromium is an important alloying metal
since 1865, limited mining only commenced in 1916 in the Bushveld Complex and in 1919 on the Great Dyke. The use and mining of chromium escalated after the conclusion of the Second World War, with approximately half of the total world chromium ore production being mined from the Bushveld Complex. In the Bushveld Complex, only the LG6, MG1 and UG2

The Kwale Operation currently accounts for approximately 65% of Kenya's mining industry by mineral output value. Kwale Operations is designed to process ore to recover three main products: rutile, ilmenite and zircon.
Description Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
CHROMIUM (Data in thousand metric tons, chromium content, unless otherwise specified) Domestic Production and Use: In 2023, the United States consumed an estimated 4% of world chromite ore . production in various forms of imported materials, such as chromite ore, chromium chemicals, ferrochromium, chromium metal, and stainless steel.
South Africa is the leading mine producer of chromium worldwide, with an output amounting to an estimated 18 million metric tons in 2023.

Many mines have chrome ore beneficiation (COB) plants, where chromium content in the ore is concentrated through washing and sorting. Washings from the COB plants can also be a source of Cr(VI). Overburden generation: Opencast chromite mining generate enormous quantities of overburden (OB). The stripping ratio varies from 1:5 to 1:10.
energy is required to smelt and refine the ore into ferrochrome. There is no point smelting a chromite ore if breakeven cannot be achieved. During chromite smelting, energy requirement and its cost depend to a large extent on the technology used in smelting the ore.

Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used. (Ores high in alumina are preferred for processing into ...
The mining objects given in concession so far, are Bulqiza chromium mine and ferrochrome smelters of Burrel and Elbasan, chromium mines in Kalimash, Kalimashi dressing plant, etc (MEI, 2017). Albania is well known for its high potential in chromium ore, comparing to other Mediterranean and Balkans countries.

Historically Kenya had focused on developing agriculture, tourism and service industries such as the hospitality industry. The country was generally mapped as an agricultural zone in previous generations; this coupled with many explorations particularly in the north east of the country that yielded nothing, led to reduced exploration for minerals and little investment in the extraction …
