| 摘 要： | 从铁矿井下废水中采集硫杆菌种，经强化培养，用以转化铁矿石中硫化物，打开溶磷通道，添加溶磷剂ＳＰ－９增加磷的溶出，使铁矿石中磷的含量降低到０．２％以下。该生物技术还可将尾矿废液作为铁－磷复合肥料进行开发，减少环境污染并扩大国产资源的综合利用。

| Abstract: | Thiobacillus collected from waste water in iron ore well was used to transform sulphide in the iron ore. The addition of phosphorus dissolving agent enhanced the dissolution of phosphorous to decrease the content of phosphorus in iron ore below 0. 2%. This biological technique may also be used to prepare iron-phosphorus composite fertilizer from waste water of the tailings so as to reduce environmental pollution, and to develope the comprehensive utilization of national resources. |
