一、蛇纹石资源及用途 蛇纹石是富含镁的硅酸盐岩石。蛇纹石矿床是由超基性岩受高温热液作用变质而成,主要组成矿物为叶蛇纹石、纤维蛇纹石等,其化学组成为3MgO·2SiO_2·2H_2O。蛇纹石含MgO最高可达40％,具有较强的耐热性能。 我国蛇纹石矿分布较广泛,主要分布在赣、皖、苏、豫、鲁、川、闽、鄂等省,已探明地质储量30亿吨,年产原矿石170万吨左右。 First, the serpentine resources and uses Serpentine is magnesium-rich silicate rock. Serpentine deposits are metamorphosed from ultrabasic rocks by high-temperature hydrothermal fluids. The major components of the serpentinite deposit are leaf serpentine and fiber serpentine, with a chemical composition of 3MgO · 2SiO 2 · 2H 2 O. Serpentine containing MgO up to 40%, with strong heat resistance. Serpentine ore is widely distributed in China, mainly distributed in Jiangxi, Anhui, Jiangsu, Henan, Shandong, Sichuan, Fujian and Hubei provinces. The proven geological reserves are 3 billion tons and the annual output of raw ore is about 1.7 million tons.
