我国是世界主要产硼的国家,而辽宁省的硼矿资源当推全国首位。我国内生硼矿的特点,一般是品位低,矿物组成、结构构造和共生关系较为复杂。目前,绝大多数化工厂制取硼砂所使用的原料都是不经选矿加工的硼矿石。因硼矿石供不应求、加工成本高,所以经济效益低。 1980年,受辽宁省化工局的委托,针对当前硼矿石加工利用所存在的问题,曾对营口后仙峪硼矿焙烧矿做过两个矿样的可选性试验,其中干式强磁选和干式强磁—浮选法均获较满意结果,为硼矿的合理开发利用找到了一条新的途径。
China is the world's major boron producing country, while the boron resources in Liaoning Province should be the first in the country. The characteristics of endogenous boron mine in our country are generally low grade, mineral composition, structural structure and symbiotic relationship are more complicated. At present, the vast majority of chemical raw materials used to make borax are non-beneficiation processing of boron ore. Due to the shortage of boron ore, high processing costs, low economic benefits. In 1980, commissioned by the Liaoning Provincial Bureau of Chemical Industry, aiming at the problems existing in the current boron ore processing and utilization, two ore samples were tested for the feasibility of roasting mine in Xiangyu, Yingkou, And dry magnetic - flotation method are more satisfactory results, for the rational development and utilization of boron found a new way.
