Ferrosilicon

The silica source for producing ferrosilicon is usually quartzites of lump size 20 to 80 mm, subjected to prewashing, crushing, and grading if needed Quartzites suitable for smelting of ferrosilicon must contain not less than 97% SiO 2 and not more than 15% Al 2 O 3 The carbon reductant is usually nut-coke of 5 to 20 mm in size, but as ....

"Sand to Chips"

Silicon can be extracted from any quartz relatively easily (you can do it, albeit somewhat dangerously since silicon is an excitable element, in your kitchen from beach sand); but to process it to the level of purity needed, then ultra-pure equipment is essential - and it's made from Spruce Pine quartz...
