Abstract:The process mineralogy study was done on primary grinding product and the reground bulk rough concentrate of lead and sulfur in a lead and zinc ore dressing plant,which found out the liberation degree of the lead and zinc minerals in the grinding products,as well as the intergrowth relationship among the minerals.In the primary grinding mineral products,the liberation degree of sphalerite is 90.40%,The liberation degree of galena is 74.72% ; In the regrinding bulk rough concentrate of lead and sulfur,the liberation degree of sphalerite is 69.69%,the liberation degree of galena is 75.45%.The separation target of this lead and zinc dressing plant can be increased through improvement of grinding size according to the study.
Keywords:lead and zinc ore  ore grinding  process mineralogy
