俄罗斯滨海铁矿可选性研究

Study of Separability of Binhai Iron Ore in Russia

俄罗斯滨海铁矿属于低品位酸性铁矿石,有用矿物主要为磁铁矿,呈浸染状、稠密浸染嵌布,且嵌布粒度很细。通过可磨度、可选性试验,对矿石选别方法、磨矿粒度、精矿及尾矿等产品指标进行初步研究,得出矿石可通过单一磁选方法选别,但需要进一步提升磨矿粒度,已达到可利用水平。

Binhai iron ores in Russia belong to low-grade acid iron ores and useful mineral is primarily magnetite,which is fine-grain disseminated or densely disseminated.By separability tests and separability tests,ore separation method,ore grinding size,product indexes of concentrates and tailings are preliminary studied and it’s concluded that the ore can be separated through sole magnetic separation method but ore grinding size should be improved further so as to achieve the utilization level.
