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.
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 excretion of this type of chromium from the body tends to be very slow which means that elevated concentrations of chromium can be seen decades later in human tissues. [23] Environmental effects. Chromite mining, chromium, and ferrochrome production can toxically effect the environment. [23]
A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill
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 mine is used by diving clubs and swimmers (the water is very clear, and there are several 'wrecks' at the bottom). There was a Mutorashanga Triathlon held here for a few years (~2000). The quarry is known as the "Green Pool." Water in the Green Pool is algae-free because of intense mineral content and it is unsuitable for agriculture.
The Seto Inland Sea in Japan is not a true inland sea but rather a body of water separating Honshū, Shikoku, and Kyūshū, three of the four main islands of Japan. The Caspian Sea is a very large, inland body of water at least hundreds of miles from the nearest part of the World Ocean (such as the Persian Gulf ) and has some characteristics of ...
