| 摘 要： | 本公司在处理中低品位硅钙质胶磷矿时,主要采用正反浮选流程,在正浮选作业中适当添加脱硅增效剂后,可以提高正浮选脱硅的效率,脱硅效率从71.82%提高到77.62%.正浮选作业从原来的一粗一精一扫中矿再选简化为一粗一精流程.

| Abstract: | In handling the medium and low grade silica-calcia bearing phosphate rock by the company,a positive-reserve flotation process was significantly involved.Adequate addition of desiliconizing synergist in the positive flotation operation resulted in increase of desilication from 71.82% to 77.62% and the positive flotation operation being simplified from the original roughing-cleaning-scavenging of middlings to roughing-cleaning process. |
