Reprocessing Tailings Dams – A systematic Approach (Part 1) Apr 02, 2014· Millions of tonnes of sulphide tailings are produced each year from base metal and gold flotation operations. Of these tailings a substantial amount is stored in tailings dams of which an example is shown in Figure 1.
After settling and selfweight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about t/m 3 due to their low G s, while for metalliferous tailings the dry density is up to t/m 3 due to their higher G s. Figures (a) and (b) show typical wet and dry density and w profiles with depth for ...
