从查明梅山铁矿高磷铁矿石中磷的赋存状态、嵌布特征及磷铁关系着手 ,进行了T f菌氧化黄铁矿生产浸出液及以此浸出液浸矿脱磷的研究。实验结果表明 ,以微生物氧化黄铁矿产酸 -酸浸脱磷的途径是可行的。 Starting from the investigation of the occurrence and distribution of phosphorus and the relationship between phosphorus and iron in high-phosphorus iron ore from Meishan Iron Mine, the production of leachate from pyrite pyrite by T f bacteria and its leaching process were studied. The experimental results show that it is feasible to take advantage of acid-acid leaching of phosphorus by microbial oxidation of pyrite.
