The Impinge Eluvial Chromium Mine is in Mashonaland Central, Zimbabwe. The Impinge Eluvial Chromium Mine was closed at the time of data entry with no known plans to re-open. Mine operations consist of 2 distinct surface and underground workings extending 1,000.00 hectares (2,471.05 acres). There is one known shaft.

However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite orMost of the world's known chromite occurs in two stratiform deposits: the Bushveld Complex in South Africa and the Great Dyke in Zimbabwe.
Nearly all of Zimbabwe's chrome production is sourced from the Great Dyke and consumed for local ferrochrome plants. Madagascar also has a small chromite mining industry. Chromite is generally produced as a by-product of PGM mining and is normally stockpiled before selling to the ferrochrome industry. Mining Companies active

Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important
Zimbabwe also has approximately 15% of the global chromite reserves and these are also mainly found within the Great Dyke. Chromite is mined throughout the Dyke as the chromite seam deposits span the entire dyke. Some of the chromite mining operations occur especially in the Darwendale, Lalapanzi and Mutorashanga areas.
A combination of poor mining methods, waste storage and disposal systems, as well as the day‐to‐day activities associated with tribute and contract chromite mining are primarily responsible for environmental problems on the Zimbabwe Great Dyke. For instance, the unsystematic dumping of waste rocks in rivers blocks channels and results in flooding, which further sterilizes agricultural land ...
The two major chromite ore producing companies in the country are Zimbabwe Alloys Ltd. (Zim Alloys) and Zimbabwe Mining and Smelting Co. (Private) Ltd. (Zimasco). In 2014, 595,656 t of copper-nickel ore was processed to produce 7,026 t of nickel.
Zimbabwe • A parliamentary portfolio committee on Mines and Energy has asked the Zimbabwean Government to lift the ban on chromite exports and rather impose an export tax on the mineral. The committee suggested that the Minerals Marketing Corporation of Zimbabwe should be allowed to export chromite as it would allow producers to recover
The Great Dyke of Zimbabwe is a layered mafic intrusion of igneous, metal-bearing rock that has been dated to approximately 2.5 billion years old. The dyke (or dike in American English) intrudes through the even older rocks of African craton, the core of oldest rocks forming the continent of Africa.
Stratiform chromite deposits are mined using predominantly underground mining methods, although some surface mining has occurred. Once mined, the chromite ore goes through various stages of processing. The first step usually involves hand sorting and screening. ... (Zimbabwe) Highly elongate linear body; Y-shaped in cross section
Chromite is a black chromium-bearing mineral, FeCr2O4.Important chromite mining countries are Kazakhstan, South Africa, Zimbabwe, and India. Chrome is needed for a variety of purposes but it is mostly used to make stainless steel.
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, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections. Chromite is isomorphous with the mineral Magnesiochromite and is easily confused with it, as they ...
Zim set for chromite export boom. Zimbabwe is poised for remarkable increase in chromite exports beginning this year, on the back of anticipated strong growth in chromite ore and ferro-chrome production, experts in the industry have said. Increased ferro-chrome output this year, projected to register 15 percent growth above 2018 production, is ...
Chromium. 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.

12%Over five hundred kiolmetres long and rarely more than ten wide, it traverses the Archean Shield of Zimbabwe (Rhodesia) from north to south. Within layered ultrabasic rocks are several seams of chromite. These are strikingly persistent and together constitute the world's largest resource of that Mineral. Keywords
Mining in Zimbabwe Today As mentioned above, the Great Dyke is one of Zimbabwe's most mineral rich mining areas and provides the largest percentage of production of the mining industries in the country. 28 million tonnes of Platinum were mined in 2011, as well as 930 billion tonnes of chromite.
Chromite grains in nearly fresh Archean komatiites from the late Archean Belingwe greenstone belt (ca. 2.7 Ga), in Zimbabwe, have diverse morphologies: skeletal and dendritic chromite is restricted to spinifex zones, whereas euhedral grains occur throughout the flows. Systematic differences in chromite compositions ate present between the
A combination of poor mining methods, waste storage and disposal systems, as well as the day‐to‐day activities associated with tribute and contract chromite mining are primarily responsible for environmental problems on the Zimbabwe Great Dyke.
Chromite is a mineral that is an iron chromium oxide. ... PGMs: PGMs mined in Zimbabwe consists of platinum, palladium, rhodium, ruthenium, iridium and osmium found along the Great Dyke from layered mafic-ultramafic intrusions extending over 550km at an average width of 11km, estimated to hold 2,8billion Mt of PGMs ore at 4g/t pt. ...
Chrome mining in Zimbabwe is mainly concentrated on the Great Dyke and it is estimated that the Dyke hosts about 10 billion tones of unproven reserves. Most of the chrome claims are located in Mutorashanga, Chegutu, Kadoma, Kwekwe and Lalapanzi. Despite the huge
Zimbabwe is the only country to have both stratiform and podiform deposits. Economicfactors like transportation and massive or disseminated type of ore are also considered before mining chromium. The deposits of the chromite are generally removed by surface and underground mining techniques.
Chromite, and by extension chromium, is mined by both large mining companies and small-scale miners in Zimbabwe. Processed chromium has a value of approximately 100 times more than newly-mined chromium. This means that many of the small-scale miners have to excavate large quantities of the product to make a living from chromium mining.

The conglomerate was not gold-bearing, although gold was late discovered and, along with chromite, is still mined in the area. Cattle, maize, cotton and tobacco are commercially farmed in the area. Banket grew as a service centre for the surrounding mines and commercial farms, and has suffered from the downscaling of chromite mining in Zimbabwe.
