Capacity: 2300t/d  Mineral: lead&zinc  Service: EPCM,solution,design and equipment supplying  It tooks only six months before the first phrases was put into production. That is never happened before so it obviously demonstrated the advantage of Xinhai EPC service.  The lead & zinc dressing plant is located in Inner Mongolia. There are three phrases during the construction. The first phrase with the capacity of 650t/d, the second is 650t/d and the third is 1000t/d. The first two phrases include crushing and dewatering and are settled at one step. The period of the first phrase was from April 2004 to October 2004. The second phrase was finished in the same year and the last phrase was operated in 2005.  The project includes test, design and equipment supply. The crushing process adopts two stages closed-circuit while grinding process adopts MQGg2727 mill and hydro cyclone. Flotation adopts one roughing and two scavenging lead & zinc beneficiation. The concentrate is used for separating lead through re-grinding classification and four times of beneficiation. After that, the tailing is used for separating zinc through one roughing and three scavenging. After four times of beneficiation, the concentrate becomes tailing which could be used for producing sulfur through one roughing, one scavenging and one beneficiation.
