Ferroalloys are mainly produced in electric furnaces, with high power consumption (approximately 5,000 kWh per ton) and require abundant and inexpensive power resources. France became a major producer of early ferroalloys, and Norway became the largest exporter of ferroalloys, based on abundant hydropower resources. In the 1970s, the consumption of ferroalloys in industrialized countries was roughly 20 kg per ton of crude steel produced; the share of the main alloying elements was: 5.5 to 6.5 kg of manganese, 2 to 3 kg of silicon, and 2 to 3 of chromium. kg.
