Methods Of Mining Silicon

What are the main methods of mining? | American ...

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Silicon - Wikipedia

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was ...

Silicon - General

One of the methods of obtaining pure silicon is mining Quartz or Silicon Dioxide(SiO2) and putting large amounts of it in an 'arc furnace' along with Carbon(C). When heated the oxygen splits from the silicon and merges with the carbon. The arc furnace is used to extract the by-products carbon monoxide and carbon dioxide. Before its official discovery it was believed that there had been a few ...
