Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 ·3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially …

The ultramafic rocks making up the Zhob Valley igneous complex have yielded small amounts of metallurgical-grade chromite since the early part of the century. From 1968-1970 a cooperative study undertaken by the Geological Survey of Pakistan and the U. S. Geological Survey, under the auspices of the Government of Pakistan and the Agency …

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. Chromite is isomorphous with the mineral Magnesiochromite and is easily ...

ABSTRACT The exploration of podiform chromites in the Indus Yarlong Zangbo suture zone of southern Tibet has proved difficult because most known deposits pinch out and …

of chromite accounted for 52% & above Cr 2 O 3 Fines grade followed by 30% least of 40 –52% Cr 2 O 3 (lumps 2% & fines 28%) grade. Mine-head closing stocks of chromite in 2019-20 were 2,411 thousand tonnes as compared to 2,253 thousand tonnes in 2018-19 . The average daily employment of labour in chromite mines during 2019-20 was 5,891 as …

Chromite occurrences in ophiolite complexes present valuable natural resources and require sophisticated geophysical exploration methods. As chromite does not exhibit significant geophysical anomalies, we propose an indirect method of detection by surveying for magnetic anomalies caused by the serpentinization of the chromite host …

A number of Chromite ore bodies were observed during the exploration. Two samples were collected from the harzburgite (host rock) and other eight samples from the chromite bearing ore bodies. All samples were analyzed to know the chromite, iron oxide, silicon di oxide, aluminum oxide, calcium oxide, magnesium oxide content, and Cr:Fe ratio.
