Abstract:Through the study of ore properties, analysis of dressing and metallurgy test, and the experience of similar mine production practice at home and abroad, a reasonable dressing and metallurgical process was designed for a gold mine in Tajikistan. The design process of ore dressing included three stage crushing with a closed one, two stage closed grinding, gravity separation and flotation; and the designed metallurgical process included cyanide leaching, washing zinc dust replacement, refining and so on. The process flow is rational and sizing of equipment appropriate, processing and metallurgical indicators after industrial application is up to engineering design standard.
