摘要
铝土矿选矿产品传统的沉降方法是加入硫酸类助剂调低pH值,再加入絮凝剂沉降,不仅增加了选矿成本,而且无机盐累积会造成对流程和工艺指标的不良影响。针对该问题,提出了铝土矿选矿产品的碱性沉降技术,采用高效碱性絮凝剂BXF可以使铝土矿精矿和尾矿在原始矿浆的pH值下完成沉降,工业应用效果良好,有利于生产成本的降低和生产流程的稳定。
The traditional settlement method of bauxite benefication products was adding H2SO4 to reduce pH value,and then adding flocculant to settle.This method not only increased the cost of dressing,and salt accumulation would result in process and process indicators variation.For this problem,this paper presented the alkaline settlement technology of bauxite benefication product,which allowed the concentration and tailing of bauxite products to complete the settlement in the original pH of the slurry using the alkaline flocculant BXF.The results showed that the technology had good effect in industrial application,which would reduce the cost of production and improve process stability.
