More than 10 million of gold tailings were stored in the tailing pond in North Korea. The average gold grade of the tailings was 1g/t, and the recoverable valuable element was gold. As the content of other categories of harmful elements was low, there was no environmental pollution hazard. Xinhai Mining Technology & Equipment Inc. provided a design of 2500d/t gold tailings flotation plant, to realize high efficient utilization of resource.
Crushing system was unnecessary for the tailings, the design included 1 stage closed circuit grinding, 1 stage roughing +3 stages scavenging +3 stages concentration, and 2 stages dewatering on the concentrate. To save energy, reduce consumption and improve resource utilization, the design adopted a series of energy saving, efficient and reliable equipment, such as LPII-φ600 Xinhai wear-resistant hydrocyclone, XPA200/150 Xinhai wear-resistant slurry pump, XPB3/2D-HH Xinhai wear-resistant alloy pump, MQGg2747 cylindrical energy saving grid ball mill and GBJ-3000 high efficiency agitation tank.
