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.
Although this mechanism is an elegant response to short-term bacterial infection, it can cause problems when it goes on so long that the body is deprived of needed iron for red cell production. Inflammatory cytokines stimulate the liver to produce the iron metabolism regulator protein hepcidin, that reduces available iron.
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.
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.
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.
The body of an adult human contains about 4 grams (0.005% body weight) of iron, mostly in hemoglobin and myoglobin. These two proteins play essential roles in oxygen transport by blood and oxygen storage in muscles. To maintain the necessary levels, human iron metabolism requires a minimum of iron in the diet.
Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms.
