why is lime added with water for gold ore sag mill

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

SAG Mill Grinding Circuit Design

Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive.In the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit

The mixture of ground material and water is known as pulp. The pulp from the SAG mill travels into a cylindrical sieve known as a trommel. The excess is recirculated again into the SAG mill via a conveyor belt system, and the undersized material is emptied into a box that feeds the ball mills to continue reducing the size for subsequent treatment.

In these cases, it is best to disperse fumed silica into the better wetting resin, then bring the rest of the formulation into this mixture. In water-reducible systems, sequence of addition is especially crucial for hydrophobic AEROSIL grades. It is suggested that the fumed silica be added into the vehicle first, without the water adjustment.
