Answer Wiki. The pulp density is adjusted to a value (t/m3) that lies between the densities of your ore and the waste rock. The heavier particles will then sink in the slurry and the lighter ones will float (sink float or dense media separation). The FeSi has to be very fine so that it does not settle easily.
