How is silicon metal produced?
The inputs to refining or smelting silicon metal are quartz sand and coke (carbon). The high-temperature refining (silicon has a melting point of 2570°F) process is energy-intensive – requiring approximately 13,000 kilowatt-hours per ton of silicon metal produced. The major producers have direct access to quartz mines and low-cost energy
