Autogenous Grinding Semi Autogenous Grinding Circuits

Figure 3 shows a typical semi-autogenous (SAG) circuit with feed coming directly from a primary crusher, and the semi-autogenous mill product going to the separation process. Many similar semiautogenous circuits are built today because they are simple and flexible, lend themselves readily to high tonnages and usually are lower in capital cost and lower in operating cost. With some ores, it is ...

SAG Mill Grinding Circuit Design - 911metallurgist

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...

Gold extraction - QueensMineDesignWiki

Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates. If the ore rock is highly ...
