MINERAL PROCESSING MILLING Introduction Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety

• The process of froth flotation involves crushing and grinding the ore to a fine size This separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurrycalled the pulp. • The pulp is processed in the flotation cells.

(Horst 1985, p. 3A5). Average grinding sizes for the ore can be brought down to 1015 microns at the very most, if using long grinding periods on a product which has already passed a 200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.
