摘要
辽宁翁泉沟含铀硼铁矿中硼（B2O3）储量约占我国总储量的一半,矿床经勘探后一直没有得到很好利用。在综合利用资料积累与地质研究基础上,认为影响矿床利用的因素主要为矿石分解状况。研究认为矿床中硼镁铁矿-磁铁矿和硼镁石-磁铁矿两种主要类型矿石中绝大部分可利用的为变质后期热液作用产生的硼镁石-磁铁矿型矿石。这种热液作用形成的矿石是有规律可寻的。为达到综合利用的目的,有必要按不同类型矿石重新圈定矿体,根据不同矿体中矿物组分,选择不同的综合利用方案。
The Wengquangou vonsenite deposit in Liaoning province makes up about half the total B2O3 reserves in the state but it is a pity that the deposit has never been developed and utilized after the exploration task ended. Data analysis and field investigation indicate that the problem rose only for lack of adequate understanding of how the ores were hydrothermally decomposed during mineralization. Though the deposit has developed two chief ore types, ludwigite-magnetite and szaibelyite-magnetite, only the latter type, as a product of hydrothermal process at the late stage of metamorphism, is usable. What types of ores the hydrothermal process would yield at the late stage of metamorphism may generally be made clear. Consequently, in order to comprehensively utilize the ores, it is necessary that the known orebodies should be re-located with the types of ores and then according to mineral composition of different orebodies, different utilization programs should be decided for the ores.
