包钢选矿厂降低铁精矿中氟含量的技术攻关

Technology discussion on reducing F content in iron concentrate at Ore-dressing Plant at Baotou Steel

为了降低铁精矿氟含量 ,通过采取控制磨矿粒度、改进浮选工艺、采用高效捕收剂等措施 ,使包钢选矿厂铁精矿氟含量由 1999年的 0 75 %降低到 2 0 0 0年的 0 6 5 %、2 0 0 1年的 0 5 8% 。

To reduce the F content in iron concentrate, some measures such as grinding ore control, flotation process improved and high-efficiency catching agent are adopted. The result is that the F content is reduced from 0.75% in 1999 to 0.65% in 2000 and 0.58% in 2001, which made good contribution to the environmental protection at Baotou Steel.
