微细粒钛铁矿选矿技术研究进展
|
摘要
综述了微细粒钛铁矿浮选药剂的种类和机理、选别设备的特点以及微细粒级钛铁矿的选别工艺。结合实际案例,分析了调整剂和捕收剂的作用机理、介绍了新设备的研制和工艺流程的创新与运用。微细粒钛铁矿选矿技术研究的现状是研制具有协同效应的组合药剂以及应用复合力场的新型设备。多数选钛厂采用磁选与浮选联合工艺选别微细粒钛铁矿。实际生产中微细粒钛铁矿的回收率低,-0.019 mm粒级钛铁矿缺乏有效的选别方法是研究过程中面临的难点。
The varieties and mechanisms of ilmenite flotation agents, the characteristics of the separation equipment and the technological process of fine ilmenite recovery of fine ilmenite were reviewed. Based on practical cases of production, the mechanisms of the regulators and collectors, ideas and innovation of new equipment developments, as well as application of process flow were fully analyzed. In recent years, the use of the flotation regent synergies to develop combination reagents and the development of new separation equipment with compound force field have been a research hot point in recovery of fine ilmenite resources. Moreover, the magnetic separation and flotation combined technological process is the widely used method for such fine ilmenite resources in most concentration plants. In industry, there is still no effective processing method for the recovery of -0.019 mm fine ilmenite, which has been become a challenge needed to overcome.
