This section discusses each of these depth. areas in more preparation (to 4 depicts a typical DMS flowsheet, showing the standard processing units of feed ensure that the correctly sized feed is presented to the separation dense medium separation (to separate particles of different minerals based on their density differences and media (to recover the heavy media for recycle and re-use). While Figure 4 depicts a common single-pass flowsheet, each material of interest can be processed using customized sequence of separation stages (i e., reprocessing of the float sinks streams at different densities and with or without intermediate size reduction sta Consequently, each material to be treated can utilize a specific flowsheet, developed through systematic testing, to allow the most effective trade-off between value recovery/waste mass rejection and cost. SGS Figure 5 depicts a photograph of the pilot scale (3 tph capacity) DMs plant at SGs can be Lakefield also uses a smaller capacity pilot-scale DMS plant (-1 tph capacity), which integrated with the 5 tph plant to allow continuous testing of a second (repass) DMs stage.
