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. [ 1 ] [ 2 ] Ferrochrome is produced by electric arc carbothermic reduction of chromite .
This is a list of countries by chromium ore production in 2023, based on the United States Geological Survey. [1] Chromium is a chemical element that is designated by the symbol Cr and has an atomic number of 24. It is usually found as the mineral chromite, from which ferrochrome is produced in a smelting process.
Current production capacity is about 33'000 tons of ferrochrome per year. [9] This product is entirely destined for export, mainly to the markets of developed industrial countries in Europe, Asia and America. FerroChrome Plant of Burrel. Built in 1979, the Burrel FerroChrome plant is one of the first investments in the minerals industry in Albania.
Chromite mining, chromium, and ferrochrome production can toxically effect the environment. [23] Chromite mining is necessary when it comes to the production of economic commodities. [24] As a result of leaching of soils and the explicit discharge from industrial activities, weathering of rocks that contain chromium will enter the water column.
Iron is also the most abundant transition metal in the human body and it is used in various processes like oxygen transport and ATP production. It plays a key role in the function of enzymes like cytochrome a , b and c as well as iron-sulfur complexes which play an important role in ATP production. [ 13 ]
The chrome contained in the ferrochrome generated as a product at the ferrochrome plant – used as an alloying material in the steel manufacturing process – is what makes the steel manufactured at the Tornio steel plant stainless. Operational safety, cost-effectiveness and eco-friendliness are characteristics of the Kemi Mine.
Systems geology emphasizes the nature of geology as a system – that is, as a set of interacting parts that function as a whole. [1] [2] [3] The systems approach involves study of the linkages or interfaces between the component objects and processes at all levels of detail in order to gain a more comprehensive understanding of the solid Earth ...
According to Carrabba the area of the Ring of Fire that Cliffs acquired in 2009 represents one of the "premier chromite deposits in the world. Chromite is smelted to produce ferrochrome which is used globally in the production of stainless steel and is categorized as a strategic metal resource by many countries. [12]
