silicon dioxide is mostly obtained by mining and purification of quartz. Quartz comprises more than 10% by mass of the earth's crust. This product will be suitable for many purposes while for others chemical processing will be required to make a purer or otherwise more suitable (e.g. More reactive or fine-grained) product.
an estimated 95% of silicon dioxide produced is consumed in the construction industry, e.g. For the production of portland cement. Other major applications are listed below.
