Where are the major iron ore deposits in China?What is the total reserves of iron ore in China?
Gangue minerals are mostly composed of quartz, SiO2 in 40-50%. but Benxi Tongyuan Fort iron ore for the autolysis of ore, the basicity (Ca+Mg/SiO2) in more than 1. And manganese 1.29-7.5% can be used instead of manganese.
Ore containing S, P impurities rarely, Benxi men's Fen iron ore containing P is very low, is the smelting of high-quality pig iron raw materials
Ore minerals are mainly magnetite and hematite, partly false hematite and semi false hematite. The structure is compact and hard, and the gangue distribution is uniform and dense. The ore dressing is difficult and the reducibility of ores is poor
Indeed, the northeast northeast iron ore iron ore is mainly in Anshan mining area, which is currently China's largest reserves of mining area, large ore bodies are mainly distributed in Liaoning province of the saddle (including large arc hill, cherry orchard, Anshan, Gongchangling and other things), Benxi (male, Finland Waitoushan, Tongyuan Fort etc.), part of the deposit located near in Jilin province calls. Anshan mining area is the main raw material base Anshan, Benxi Iron and steel.The main characteristics of Anshan ore: in addition to rare high-grade ore, the reserves account for about 98% of the ore, iron content of 20-40%, an average of about 30%. Must after dressing treatment, selection of more than 60% iron content.
