It is also the only continuous gravity concentrator available that utilises the patented fluid-bed feature for ensuring separation of high and low specific gravity minerals. This fluidisation feature also ensures that the feed, concentrate and tails will not plug, bridge or pack as can happen with un-fluidised gravity systems. MT3500 Shaking Table

Figure 1.1: Spiral Concentrator (Mine-Engineer, 2015). In this experiment, three samples with fractions of ilmenite and silica are separated using a wash-waterless spiral. For good separation, the difference in specific gravities (SG) should be at least 1.0. This is true for ilmenite (SG = 4.72) and silica (SG = 2.65); the difference in SG's ...
