Feb 06, 2009 · 1. Introduction [2] The Oman ophiolite is one of the largest (about 30,000 km 2) and bestpreserved fragments of fossil oceanic lithosphere presently exposed at the Earth's is composed of a wide diversity of ultramafic to mafic rocks. The precise chemical composition, distribution, and contact relationships of these rocks, together with the nature of their alteration products ...

Chromite Ores from Oman are mainly loed in the mountainous region of Sohar, Somail and Sur. The quality of metallurgical grade chromite ores from Somail is the highest in terms of Cr2O3 content. Typical grade of metallurgical grade are shown below, with a Cr:Fe ratio of : 1 minimum. The grade from Somail region is from 32% to 42%.
Chromite occurrences in ophiolite complexes present valuable natural resources and require sophistied 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 rock, which contains magnetite developed through .

Exploration and Operations Geologist at Oman Chromite Company. BSc in Earth science/ Geology from Sultan Qaboos University (SQU). I am always looking for a challenging job opportunity in a recognized organization.
Chromite deposits in the northern Oman ophiolitic complex occur in three structural contexts,, (1) at the base of the cumulate series, (2) in the top kilometer of the mantle sequence, and (3) in the deeper parts of the mantle. Types 1 and 2 are characterized by the diversity of interstitial silies where in decreasing order of abundance olivine, clinopyroxene, orthopyroxene, plagioclase ...
Ultramafic systems are often synonym of high chromium (Cr) content in rocks, which is naturally leached to surface and groundwater. Due to this natural enrichment, ultramafic areas are massively mined. The mining process includes exploitation and beneficiation activities, in which large amount of metalrich residues, such as overburden, waste rock and tailings, stored in open air, are produced.

Jul 01, 2013 · According to the official Ministry of Information website from the Government of Oman, Omanet, the country is poised to embark on the next phase of an extensive mineral exploration drive for new chromite ore deposits "that promises to sustain the flow of feedstock for the country's rapidly expanding ferrochrome smelting industry.".
Oman's main copper reserves are in the Suhar area on the Al Batinah coast. The processing of ore at the Suhar complex, operated by the governmentowned Oman Mining Company, began in 1983. The production of chromite by the Oman Mining Company also began in 1983 in the Suhar area. Exports of the Oman Mining Company are primarily destined to the ...
The Semail Ophiolite of the Hajar Mountains of Oman and the United Arab Emirates is a large slab of oceanic crust, made of volcanic rocks and ultramafic rocks from the Earth's upper mantle, that was overthrust onto continental crust as an ophiolite. It is loed on the eastern corner of the Arabian Peninsula and covers an area of approximately 100,000 km 2.
The Societe Internationale Forestiere et Miniere du Congo (FORMINIERE) obtained exploration rights in the area and had evaluated the most important prospects by 1925. FORMINIERE then obtained exploitation rights for its subsidiary company, La Societe Miniere de la Tele. No further information about the two companies was available beyond what is ...

Noront Resources plans to develop domestic production of ferrochrome from Ontario's Ring of Fire chromite deposits. The mature industrial and regulatory environment in Ontario supports an environmentally responsible approach to design and operation of a smelter in Sault Ste. Marie.
Oman is a major exporter of Chromite Ore, accounting for 10% of the total world production of this mineral. Abundant midgrade Chromite Ore deposits, coupled with consistent supply of electrical energy from Oman grid and proximity to Sohar port makes this venture ideally positioned to showcase the capability of Oman as a leading supplier of ...
