钛白粉是现代工业中广泛应用的一种白色颜料,钛铁矿一直作为生产钛白粉的原料。钛铁矿还可以加工成钛金属,作为钛合金的添加剂,而钛合金是现代超音速飞机、火箭、导弹和航天飞机制造的必备材料。
在中国,钛铁矿常与磁铁矿伴生,大多存在于品位较低的磁铁矿尾矿中。尾矿粒度细,含泥量大。所有这些都需要组合处理技术来达到选矿指标。过去采用的是“重选+脱硫浮选+电选”。但该工艺流程复杂,重选下限约为30微米,细粒钛铁矿浪费严重。TiO2最终回收率仅为10%左右,严重影响了选矿厂的选矿效率和效益。鉴于这些特点,SLon公司将原有的重选改为磁选。金博宝世界杯买球1994年以来,通过对钛铁矿选矿的一系列研究,我公司技术人员对磁选机进行了相应的改进。首先,针对钛铁矿回收率低的问题,我们的技术人员调整了磁结构和磁场强度,增加了分离面积和分离时间。有效分离尺寸大大减小到20μm。 Compared with the gravity separation operation, the recovery rate is more than 20% higher than before. And SLon magnetic separators also perform better among similar magnetic separators. Secondly, according to the characteristics of magnetite tailings, a pulsating mechanism with large stroke and high impact times has been adapted, which effectively improves the concentrate grade while desliming. This unique design lays a good foundation for the subsequent flotation. Finally, in order to reduce the cost of beneficiation and save space, SLon has developed the world’s largest industrial model SLon-4000 HGMS at that time, whose processing capacity can reach up to 400 tons/hour. After many years of practical application, the updated Ilmenite HGMS has completely took place of gravity separation, and simplified the previous processing technology into magnetic separation+desulfurization flotation. The total recovery rate of TiO2 can reach about 50% by a coarse-to-fine technique, which is nearly 30% higher than before. SLon WHIMS is efficient and simple to operate with a low mineral processing cost, which has created considerable economic, social and environmental benefits for mining enterprises. So far, with more than 300 units of SLon machines serving the ilmenite plants, SLon has become the preferred brand and obtained unanimously recognition by customers.
