Ferroalloys Processing Equipment
The process by which ore is converted to a ferroalloy contains a number of steps. These include mining of the ore; preparing the ore by processes such as crushing, screening, washing, grinding, or milling; and sometimes applying beneficiation processes such as flotation, followed by smelting and refining. This chapter describes the equipment

Silicon Wafer Manufacturing Process
The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.

Silica
Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics.
