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 .
Similar to light zonation, thermal stratification or thermal zonation is a way of grouping parts of the water body within an aquatic system based on the temperature of different lake layers. The less turbid the water, the more light is able to penetrate, and thus heat is conveyed deeper in the water. [ 17 ]
Production of ferrochrome is observed to emit pollutants into the air such as nitrogen oxides, carbon oxides and sulfur oxides, as well as dust particulates with a high concentration of heavy metals such as chromium, zinc, lead, nickel and cadmium. During high temperature smelting of chromite ore to produce Ferrochrome, Cr-III
A body of frozen water constrained by topographical features: Ice sheet: 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 ...
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.
But when water finds its way into such salt workings, it erodes the salt pillars supporting the roof, making the ceiling area collapse and causing subsidence to a greater depth. [ 10 ] [ note 1 ] Brine extraction underneath the River Weaver in Cheshire accounted for the development of several lakes along the course of the river.
The Black Sea is an example of a body of water with a prominent chemocline, though similar bodies (classified as meromictic lakes) exist across the globe. [4] [5] Meromictic lakes are the result of meromixis, which is a circumstance where a body of water does not fully mix and circulate, causing stratification. [1] [6]
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.
