Manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such
The first step, therefore, is silicon mining and purification. Among many other things, this requires energy. Energy is one of the inputs of the mining and purifying process. The output is purified silicon, which gets shipped to a computer chip factory. The computer chip factory then takes the purified silicon and makes it into a crystal wafer ...
need for silicon also increases. Silicon is one of the most used materials in these two industries. It is an inexpensive and abundant semiconductor. However, the process of producing pure silicon adds to the cost and most people do not understand how it is done. One of the first steps of producing silicon is a process called carbonthermic ...

The major environmental impacts associated with silicon derive from its mining. Carbon monoxide is a byproduct of the basic process whereby silicon is prepared from silicon dioxide, but this is a negligible source of atmospheric carbon, compared to the amount generated by combustion of fossil fuels.
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
Silica sand mining. Southeastern and south central Minnesota and southwestern Wisconsin have extensive deposits of sand that meets the specifications required for hydraulic fracturing, or "fracking," a drilling method used for natural gas and oil wells. Mining of these deposits has been occurring in the region for many years, however recent ...
Silicon is used in the manufacture of transistors, solar cells, rectifiers and microchips. Silicon dioxide (SiO2), silicon''s most common compound, is the most abundant compound in the earth''s crust, and comprises roughly 14% of the earth''s crust. SiO2 is mined both as sand and as vein or .
Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation. Sand mining is a direct .

Wafer — also called a slice or a substrate, is a thin slice of a crystalline silicon. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as dopingor ion implantation, etching, deposition of various materials, and photolithographic patterning.
