概述硼镁铁矿-硼镁石-磷铁矿(或硼镁铁矿化硼镁石-磁铁矿)矿石类型是我国接触变质硼矿主要矿石类型之一。经选矿之后可获得硼镁铁精矿独立产品。硼镁铁矿属于含铁镁的硼酸盐,具有稳定的化学成份。对于硼镁铁矿的硼铁分离成为硼、铁综合利用的重要研究课题。一九五八年以来,国内一些科研单位进行过不少研究工作,主要方法为:酸、碱法直接提硼-硼渣提铁,该方法无论碳碱法、碳氨法、碳酸法或硫酸法提硼均可取得较好的效果,硼的提取率均达90％以上,但提硼后的硼渣由于提硼焙烧时加入大量
Summary The ore type of bauxite-boehmite-phosite (or boehmite-boehmite-magnetite) is one of the major ore types in China that are exposed to metamorphic boron. After the beneficiation can be boredomite concentrate independent product. Boronite is a borate containing ferrous magnesium, with a stable chemical composition. Boron and iron for the boron-iron separation boron, iron comprehensive utilization of the important research topic. Since 1958, some research institutes in China have carried out many research work. The main methods are as follows: acid and alkali are directly added to boron to extract iron from boron slag, and the method does not matter whether the carbon and alkali method, the carbon ammonia method, the carbonation method or the sulfuric acid France to mention boron can get better results, the extraction rate of boron reached more than 90%, but after the boric acid boron to mention boron as a result of adding a large amount of roasting
