feeds, and recent large cyclone developments allow treating materials with top sizes as coarse as 100 mm and as fine as 05 mm Major developments in the dense medium technology include: (Wills, 1988; Hillman, 2003) • 1858 – Bessemer (UK): First dense medium process patent to remove coal...
Dense-medium cyclone tests in 4- and 8-inch-diameter units have shown the ability of cyclones to make sharp separations down to 100 mesh when washing coals of a finer top size than normally fed to dense-medium cyclon The reduced top size of the feed apparently allows the finer size particles to report to the proper product by reducing the effect of very coarse particles in the congested separa...
