瑞典马尔姆贝厄特(Malmberget)铁矿位于北极圈北约70公里,是一年产矿石约450万吨的高品位矿石矿山。矿石含铁60—64%。除少量赤铁矿外,大部分为磁铁矿。矿体原为一坚固的整体,但因花岗岩的侵入,发生了次生变化,结果形成为包含不同类型矿石的长矿体。矿体大部分含磷,最东部含铁量很高(63%),密度也大(4.7吨/米~3),而含磷百分比较低。 The Malmberget iron ore mine in Sweden, located about 70 kilometers north of the Arctic Circle, is a high-grade ore mine with an annual output of about 4.5 million tons of ore. Iron ore 60-64%. In addition to a small amount of hematite, most of the magnetite. The ore body was originally a solid whole, but due to the intrusion of granite, a secondary change took place and the result was a long ore body containing different types of ores. Most ore bodies contain phosphorus, with the highest iron content (63%) in the eastern part and large density (4.7 ton / m ~ 3), while the phosphorus content is low.
