Dynamic froth stability of copper flotation tailings

A processing plant in Chile has been reprocessing copper flotation tailings from two historic and one fresh tailings dams since 1992. The grade ranges from 0.12 Cu for the fresh tailings to 0.27 Cu for the historic tailings. The feed from these tailings dams to the plant contains a high proportion of fines, approximately 50 , by mass, of the material passing 10
