The Enrichment Ratio is calculated by dividing the concentrate assay in Table 1 by the feed assay: Enrichment Ratio = 20.0/2.09 = 9.57 This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves
The choice of flotation cell size best suited to any specific application must consider the pulp flow rate, the number of parallel modules in the flotation section, the minimum number of cells in each row required to eliminate pulp short circuiting and the required pulp residence time. Economic considerations favour large cells in rougher scavenger operations since it is this part of the
14/12/2015· 3) Concentrate Zone: In the concentrate or top zone, the material being enriched is partially separated by a baffle from the spitz or concentrate discharge side of the machine. The cell action at this point is very quiet and the mineral laden concentrate moves forward and is quickly removed by the paddle shaft .
11/01/2016· This will be handled on 63 roughers run in parallel, and 18 cleaners, or an average of approximately 57 tons per roughing cell, or 45 tons per cell for roughing and cleaning. Some tests have shown little difference in recovery, whether running 45 tons to the cell or 65; but the recoveries commence to decline as soon as the feed exceeds 75 tons.
Dissolved air flotation provides thickening of sludges by encouraging the solids to float to the surface, rather than allowing them to sink to the tank base as with gravity thickening, where they can be removed by a skimmer. DAF is applied when the sludge solids are neutrally buoyant and so cannot be readily ...

16/06/2017· Thickening is a process where a slurry or solid liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water . The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.
