Ferroalloy resources

In addition to the prevalence of silica in the smelting of ferroalloys, most of them are concentrated in a few areas. For example, 90% of chrome ore is distributed in southern Africa, and manganese ore is stored in South Africa and the Soviet Union. Most of the ore is in the form of oxides or oxygenates (such as chromium, manganese, tungsten, nickel, vanadium, titanium, etc.) and some are sulfides (such as molybdenum). These ores have different grades, and most of them require enrichment. China's tungsten ore reserves rank first in the world. Nickel and molybdenum resources were identified in the 1970s with large reserves. The vanadium-titanium magnetite in Panzhihua and other places contains a large amount of vanadium and titanium resources. Manganese ore has considerable reserves in Hunan, Guangxi, Guizhou and other places, but the grade is low.
