Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore …

When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold. During World War I and World War II, Oregon's contribution to the domestic production of chromite varied from one-fifth to one-quarter.

Fig 1 Fe-Cr phase diagram. Around 85 % of the chromite (chrome ore) mined is used in metallurgical application, namely stainless steels, low alloy steels, high strength alloy steels, tool steels, some maraging steels (high strength alloy steels of the precipitation hardening type), and high performance alloys such as chromium-cobalt- tungsten (or molybdenum) alloys, nickel-chromium …

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. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...

grade with Cr/Fe ratios of typically 1.7 or less. Early producers exploited reserves with Cr/Fe ratios of >3, but following the advent of the argon oxygen decarburization (AOD) process that permitted charge chrome alloy grades The impact of platinum production from UG2 ore on ferrochrome production in …

Both grades comfortably meet the normal specifications for South African metallurgical chrome ore concentrate, and are produced by reprocessing used high-grade foundry sand from foundries. Typical specifications for Clover Alloys' two grades of metallurgical chrome ore concentrate are as follows:

For conducting a mining project's break even analysis, you first need to know about the operational expenses (OPEX).When the OPEX is known, you can calculate the mineral's cut off grade, which is the break even grade, below which it is not economically viable to mine the ore.To find out how I come up with the cost price per tonne (OPEX) if a feasibility study isn't available, I refer you ...

Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.. Increasing amounts are coming from Russia and

Samancor Chrome Mines. With low electricity prices, South Africa has been able to expand chromite and ferrochrome production more or less continuously since the AOD process was developed in the 1960s to use ferrochrome smelted from lower-grade ores.

What is Chromium? Chromium, a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point, is a silvery white, hard, and bright metal plating on steel and other material. Commonly known as chrome, it is one of the most important and indispensable industrial metals because of its hardness and resistance to corrosion.

Chrome grade Cr/Fe Concentrate Product 1,38 Smelting of Chromite The production of high carbon ferrochrome is carried out by reducing the chromite ore with a carbonaceous reductant in submerged arc furnace. Conventional smelting in South Africa is smelting ore without any agglomeration of the ore.

The chrome ore resources are also higher grade than in other parts of the world, with an average chrome to iron ratio of 2:1. ACF has a very unique resource, in that it is one of very few alluvial chromite deposits.

What Is Chromoly Steel? Chromoly steel is a type of low alloy steel that gets its name from a combination of the words "chromium" and "molybdenum" – two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost.

Cost analysis of chrome ore reduction is one of the important issues facing ferrochrome producers in today's competitive environment. Much of this depends on quality and various ratios in the actual ore. The latter can have a direct bearing on electricity consumption and optimum efficiency of the furnaces. While the industry has been successful in reducing costs by designing larger and more ...

In all rare metals, the importance and scarcity of chrome ore and scarce are most obvious, which is at the top of "strategic metals". The chrome ore is mainly used in the production of stainless steel and various kinds of alloy steel in the form of ferroalloy (such as ferrochrome), which has the advantages of strong hardness, wear-resisting, heat-resisting and corrosion resistance.

Chrome plating is done in very highly concentrated (about 32 oz./gal) chromic acid, H 2 CrO 4 -- "hexavalent chromium" -- the stuff that made Erin Brockovich a word. If a neighborhood child develops cancer from any cause whatsoever and his/her parents find out that you were chrome …
