滇池周围地区风化磷矿石经擦洗脱泥可得到优质磷精矿，是生产高浓度磷肥的理想原料。该地区到１９９３年底已投产竣工的擦洗厂处理原矿能力已达３００～３５０万ｔ／ａ，已成为我国重要的磷矿基地。文章对已建成投产的擦洗厂的工艺流程和选矿设备、生产指标进行了全面介绍，并对生产实践中暴露出来的问题进行分析、讨论，以求今后的擦洗厂设计更加完美。
Weathered phosphate rock Dianchi Lake area scrubbing off the mud can be obtained high-quality phosphate concentrate, is the ideal material for the production of high concentrations of phosphate fertilizer. The area has reached the end of 1993 completed scrubbing plant processing capacity has reached 300 to 350 million t / a, has become an important phosphate rock base in China. The article has introduced the technological process, beneficiation equipment and production index of the scrubbing plant which has been completed and put into operation, and analyzed and discussed the problems exposed in the production practice so as to perfect the design of the scrubbing plant in the future.
