根据黄岗锡铁矿的物质组成及其基本工艺性质,采用以“磁-浮-重”和“造球-预焙烧-还原挥发”为主体的联合工艺流程,使得矿石中的各有益元素得以有效分离。获得铁、锡、钨、锌、砷等合格精矿以及部分锡钨富中矿和锡贫中矿。该试验研究首次打通了该资源综合利用的工艺流程,技术先进可行。按照试验结果进行的经济效果估算表明,开发利用黄岗锡铁矿,其经济效益是好的。
According to the material composition of Huanggang tin iron ore and its basic technological properties, the combined process of “magnetic-float-heavy” and “pelletizing-pre-roasting-reduction volatilization” is adopted to make each beneficial element in the ore effective Separated. Access to iron, tin, tungsten, zinc, arsenic and other qualified concentrate as well as part of tin-rich tungsten ore and tin poor mining. The pilot study for the first time opened up the process of comprehensive utilization of resources, advanced technology available. According to the test results of the economic results show that the development and utilization of Huanggang tin iron ore, the economic benefits are good.
