As we all know, re-election of gold ore beneficiation tailings beneficiation plant will be to maximize the quality of the concentrate increased, after several Tailings Gold basically very little, and piled up. The content of associated low-grade gold ore in the piled waste tailings has been increasing over the years. In order to improve the economic benefits of the concentrator, it is necessary to re-mineralize the long-term piled tailings. Among these tailings, due to long-term pile-up, the gold content is too low and the associated elements are many, which makes it difficult to remineralize. According to the actual situation of the user, the design process has been designed with two major processes: amalgamation -flotation and centrifugal beneficiation-flotation. The process is simple, the investment is small, the effect is quick, and the finished product can be separated on the spot. Gold significantly improves the economic benefits of the mine.
