Abstract: Yichang Phosphate Mine is one of the five major phosphate mining bases in China. The phosphorus chemical industry cluster has been gradually formed around the advantages of phosphate ores resources. Green mining technology in Yichang Phosphate Mine is in the forefront of the China，and the green mining development demonstration zone has been formed. In order to popularize the sewage treatment technology and experience in Yichang Phosphate Mine green development demonstration area，the water treatment technologies in the mining area，such as multistage sedimentation system of mine water，floccu⁃ lant phosphorus removal technology，domestic sewage purification system，on-line water quality monitor⁃ ing system are introduced from the aspect of water quality，and ecological compensation system. The imple⁃ mentation of a series of measures has ensured that the water quality of the Eastern Branch of the Huangbai River Basin meets the standard，and established a long-term mechanism for the development of green min⁃ ing industry. The sewage treatment method and guarantee system in phosphate ores area are worth popular⁃ izing in the construction and development of green mines.
