新疆磁海铁矿是一个富硫、富钴的磁铁矿矿床。矿床中的钴,主要产于黄铁矿、磁黄铁矿等硫化物中,并有钴的独立矿物辉砷钴矿和斜方砷钴矿。磁铁矿矿石中含钴较高,个别富硫化物磁铁矿矿石中钴可达0.16%,达到综合利用价值。对磁海铁矿床中钴的产出特征、化学成分、赋存状态研究,结合铁和钴的元素地球化学性质,认为该矿床的成矿物质来源较深;铁和钴在岩浆-热液成矿过程中属于不同阶段的产物,钴趋于在热液晚期阶段富集。
Magnetic sea iron ore in Xinjiang is a sulfur-rich, cobalt-rich magnetite deposits. The cobalt in the deposit is mainly produced in sulfides such as pyrite and pyrrhotite, and has cobalt independent minerals such as arsenic cobalt and arsenopyrite. Magnetite ore contains high cobalt, cobalt-rich magnetite ore up to 0.16% of cobalt, to achieve comprehensive utilization value. Based on the studies on the characteristics, chemical compositions and occurrences of cobalt in the magnetic sea-iron ore deposits and the elemental geochemical characteristics of iron and cobalt, it is considered that the ore-forming materials of this deposit are of deep source. Mineralization belongs to the different stages of the product, cobalt tends to enrich in the late stage of hydrothermal.
