· The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods In ball mills the theoretical void space is around 42% to 43% It has been found that as grinding rods wear a 4″ or 4½ rod will generally break up at about 1½

Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons specifically to enable ore handling and concentrates to be transported easily allow further processing to occur and to dispose of the gangue The water extracted from the ore by dewatering is

· As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp then drying and weighing the ore With these two weights formula 2 may be used to obtain K and then formula 1 to convert to S the specific gravity A volumetric flask of one liter capacity provides the necessary accuracy In laboratory work the ore should be ground wet to make a suitable pulp This method does not give the true specific gravity of the ore
