Mining processing and transporting sand generate large quantities of silica dust which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil commonly called "fracking " has led to boom in sand ...

For maximum purity, a chemical process is used that reduces silicon tetrachloride or trichlorosilane to silicon. Single crystals are grown by slowly drawing seed crystals from molten silicon. Silicon of lower purity is used in metallurgy as a reducing agent and as an alloying element in .

Mining is a risky process though. It not only takes heavy lifting from the mining chips themselves, but boatloads of electricity, powerful cooling, and a strong network connection.
