The smelter will process ore mined from Noront's chromite deposits in the James Bay region to be converted into a semi-finished ferrochrome product that will be floated out of the Sault's port to U.S. stainless steel manufacturers.
The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning leather. It is also sometimes used as a gemstone.
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.

Ferrochrome is manufactured by conducting carbothermic reduction of iron magnesium chromium oxide under high temperatures. Iron-chromium alloy is produced by the reduction of Chromium Ore by the application of coal and coke. This reduction process requires heat which comes from the electric arc of the furnace.
Chromium(VI) is mainly toxic to organisms. It can alter genetic materials and cause cancer. Crops contain systems that arrange the chromium-uptake to be low enough not to cause any harm. But when the amount of chromium in the soil rises, this can still lead to higher concentrations in crops.
Metallurgical grade chromite is being hit hard, and at the time of writing metallurgical grade chromite prices have halved and are currently $130-150/tonne, for 40% Cr2O3South African North West, friable, lumpy, FOB. This has fallen over the last four to six weeks from a level of $320-350/tonne, same basis.
Chrome is also used in the chemical and foundry industry, this is houses small in comparison to the stainless steel industry. CRU estimates that 75% of global chrome resources are in South Africa and accordingly South Africa is the largest chrome concentrate producer.
Foamed slag has been used as a lightweight aggregate for Portland cement concrete. Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material. and granulated slag have also been used as sand blasting shot materials.
Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.
Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore (an oxide of chromium and iron) is reduced by coal and coke to form the iron-chromium alloy. The ferrochrome solidifies in large castings, which are crushed for sale or further processed.
Chromium is chiefly obtained from the mineral chromite. It is mined in South Africa, Kazakhstan, India, Albania, and Turkey.
Chromium is used in stainless steel, and other alloys. Chromium plating, for example on cars and bicycles, produces a smooth, silver finish that is highly resistant to corrosion. The metal is also widely used as a catalyst. Chromium compounds are valued as pigments for their vivid green, yellow, red and orange colors.

Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness.
Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
Chromite ore has a spinel structure with a general formula of (Fe,Mg)O. (Cr,Al,Fe)2O3. The content of Cr2O3 for metallurgical-grade chromite ore is in the range 42–55% and the chromium-to-iron ratio is higher than 1.5.
Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. The most important use of chrome is in production of high-strength alloys and alloys which are heat, abrasion, corrosion and oxidation resistant.
Although its primary origin is ultra-mafic rocks such as peridotites, chromite is also found in metamorphic rocks such as serpentites.
