The Mineral chromite 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.
The mineral chromite is widely disseminated in small quantities in the serpentine of Bare Hills and Soldiers Delight, but is is only at a few places that it occurred in payable quantities. These bodies of richer material are very irregular in size and shape, and it is very difficult to determine their value or extent.

Em 2003 a produção brasileira foi de 405 mil toneladas contendo 161 mil toneladas de Cr 2 O 3 . Os principais depósitos são encontrados na Rússia, África do Sul, Turquia, Filipinas e Cuba .
Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.
MINERAL PROFILE EASTERN VISAYAS REGION 2019 3 . II. LAND AREA AND MINERAL POTENTIAL . The region has a total land area of 2,225,343 hectares. The total area covered by approved mining rights is only 2.23% or 49,581.7565 hectares of the total land area of the region. It is important to note that out of the region's total land area, only
The discrepancy between the observed relationship between discovery order and deposit size in mineral deposits is due in part to the difference between mineral exploration and oil plays where the explored area is a relatively straightforward geologic basin whereas for minerals there can be complex geologic settings within a permissive tract.
A mineral that produces two differently oriented planar surfaces when fragmented. The first direction is labeled 1, the top of the block. The second direction is labeled 2, the left side of the block. The right side of the block is very uneven, not flat (planar) so cleavage is absent in the third direction, perpendicular to the first two ...

Chemical-grade chromite contain large amounts of iron, which often results in Cr/Fe ratios from 1.5 to 2.1, although the total amount of chromium ranges from 40-46% Cr2O3. Chromite ore is the only commercial source of chromium in thel industries . It occurs as a chromium spinel, a complex mineral containing chromium, iron, aluminium and magnesium in changeable …
Podiform chromite deposits are characteristic of the ultramafic complexes of the ophiolites. In the Limassol Forest Plutonic Complex, one of the two plutonic complexes of Troodos ophiolite, Cyprus, the deposits are located dominantly at the periphery of the serpentinite body either close to the contact between the serpentinized harzburgite (Bastite Serpentinite) and a highly …
mineral resources. Metals, nonmetals, and energy resources abound in mountains, plains, coasts, and even in shoreline areas. Among the metallic minerals found locally are chromite, copper, gold, iron, lead, manganese, mercury, molybdenum, nickel, and zinc. The mining industry in the Philippines produces wide variety of minerals from

Chromite is important to a number of industries, but is fundamental to the production of stainless steel, and was placed on Canada's Critical Mineral list. Canada does not currently have a primary producer of chromite. Over 80% of the World's chromite is produced by four countries, South Africa, Kazakhstan, India and Turkey.

Project objectives are to develop a modern probabilistic quantitative mineral resource assessment of Puerto Rico, U.S. Islands and adjacent geologically similar areas that examines the potential for minerals-based economic development and trade within the region.
Massachusetts isn't particularly well known for its rockhounding, but for a relatively small state it packs quite a few good rockhounding sites and interesting minerals within its borders. The geology of the state is dominated by vast basalts cut by the Connecticut River, resulting in the exposure of many interesting finds such as agate and …
Chromium is largely used as alloying elements in steels for production of stainless steels. It is added in form of ferro-chromium, which is presently imported from Russia and Germany to meet the need of Nigerian Steel Industry. Chromite ore (FeOCr2O3) is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of …
Chromite is most commonly found as an accessory mineral in iron- and magnesium-rich igneous rocks or concentrated in sediments derived from them. It occurs as layers in a few igneous rocks that are especially rich in iron and magnesium. Almost pure chromite is found in similar layers in sedimentary rocks.
The Mindanao Chromite Chromium Mine is in The Philippines. Production output of the Mindanao Chromite Chromium Mine was considered to be small size. The ore mined is composed of chromite, asbestos and magnesite. The host rock in this area is serpentinite.
Foundry sand use of chromite is a modern application. Sand is used to contain molten metal in a desired shape until the metal has solidified. Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral.
