Toronto, Ontario–(Newsfile Corp. – March 28, 2018) – KWG Resources Inc. (CSE: ) (CSE: KWG) (OTC: KWGBF) (FSE: KW61) ("KWG") has received Letters Patent No. 32526 and Author's Certifie No. 100393 issued by the Kazakhstan Patent Office for PRODUCTION OF CHROMIUM IRON ALLOYS DIRECTLY FROM CHROMITE ORE. About KWG: KWG is the Operator of the Black Horse Joint .
The rocks that contain more than 90% of chromite with olivine and/or pyroxene are called Chromitite (AlChalabi, 2004). According to (Craig Vaughan, 1994) Chromium ore that associated with mafic and ultramafic rocks have two modes of occurrence as following: Stratiform chromite: This type contains over 90% of chromite resources. These deposits consist of .

Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium. In its natural form it occurs in solid solution with other minerals in the spinel group, .
Chromite. Chromite ore is predominantly used in the production of ferrochrome – an alloy of chrome and iron containing between 50% and 70% chromium. The production of steel is the largest consumer of ferrochrome, especially stainless steel production which contains between 10% and 20% ferrochrome content. The process of chromite ore mining ...
The chromite ores from the four deposits studied show a varying composition and a variety of physical properties due to their modifiion by secondary processes — metamorphosis and ancient chemical composition, most of the chromite ore samples after averaging come up to the required standard for the production of normal types of chrome magnesite parts. As far as this property ...
Market Brief. Chromite is the commercial name for iron chromium oxide (FeCr 2 O 4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron its purest form, chromite comprises chromium (Cr 2 O 3) at 68% and iron oxide (FeO) at 32%.. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite.
Domestic Production and Use: In 2019, the United States was expected to consume 4% of world chromite ore production in various forms of imported materials, such as chromite ore, chromium chemicals, chromium ferroalloys, chromium metal, and stainless steel. Imported chromite ore was consumed by one chemical firm to produce chromium chemicals. .
Ferro chrome. production for metallurgical appliion such as stainless steel, uses up to 90% of the world's chromite output. Chromite output worldwide is approximately 20 million MT per year. PRODUCERS: The major producers of Chromite ores are South Africa (supplies approx 50% of world chromite ore), Kazakhstan, India, Turkey, Zimbabwe ...
The Voskhod podiform chromitite is one of more than 30 chromitite deposits that collectively form the Main Ore Field (MOF) within the Kempirsai Massif, in Kazakhstan. The MOF is the largest podiform chromitite orefield in the world. The Voskhod deposit, encased in a serpentinised dunite halo, is situated within harzburgite units that comprise the mantle sequence of the Kempirsai ophiolite.

· Chromium is found mainly in chromite. This ore is found in many places including South Africa, India, Kazakhstan and Turkey. Chromium metal is usually produced by reducing chromite with carbon in an electricarc furnace, or reducing chromium(III) oxide with aluminium or silicon.

· Chromium Demand. Over 90% of mined chromite ore is converted to ferrochromium an alloy produced in an electric furnace using chromite, iron or iron ore and carbon .
Chromium is commercially extracted from the commonly found ore, Chromite, which is an iron chromium oxide (FeCr2O4). It is also the main source of chromium for chromium pigments. Chromium ores are majorly found in Zimbabwe, South Africa, India, Kazakhstan.
This chromite was, and still is, recognized as mining area with the finest quality in the world due to its high chrome to iron ratio that commonly exceeds :1 with best grades in excess of :1. This places Albania along with Kazakhstan and Turkey as countries that produce high grade (+38% Cr2O3) and high quality premiumpriced direct shipping ore that goes into production .
Global – Chromite Mining and Processing Economics. The value of the mineral chromite is in its content of the base metal chromium. The value of chromium is in its industrial appliions, especially when alloyed with iron to produce a wide variety of steels that are more durable largely due to their corrosion resistance.
