What Is The Effects On Silicon Mining

Silicon Si is the second most abundant element in the earths crust after oxygen with most of the silicon existing in various forms of silicon dioxides silica or silicates such as quartz. In soils these minerals undergo chemical and physical weathering, which results in the release of Si in solution, which then either combines with other ...
