The quartz is sent to a thickener of 40 m diameter for dewatering so that the quartz can be concentrated. The quartz suspension enters the thickener at a flow rate of 1.6 m.s and is 0.05 vol% quartz. A stream of clarified water is drawn out of the overflow at 1.3 m.s and recycled, and the remaining quartz and water is removed via the underflow. Calculate and plot the quartz flux due to settling, Jset, as a function of volume fraction, p. The required units for flux are mm-s, and volume fraction should be plotted from p=0 to p=0.5, in increments of 0.025. Show your working for p = 0.1. (assume Stokes settling regime applies) Calculate and plot the net quartz flux in the overflow, Jo, and underflow, Ju, on the same graph. The required units for flux are mm.s, and volume fraction should be plotted from p = 0 top = 0.5, in increments of 0.025. (assume Stokes settling regime applies) Show your working for p = 0.1. Determine the volume fraction of feed to operate a critical loaded thickener under these conditions.
