Comminution An Overview Sciencedirect Topics
semi-autogenous grinding mill. It is a rotating barrel in which ore is broken by ore pieces and steel balls falling on ore as they are lifted and fall off the moving circumference of the barrel. autogenous grinding mills are similar but without the steel balls. the mills are fed and grind continuously.pre-grinding ahead of a concentrate grinding ball mill. replacement of rod mills. replacement of crushing stages combined with pre-treatment for fine grinding. supplementing pebble crushing in an autogenous milling circuit.the mill includes a primary crusher, a conventional semi-autogenous mill and two ball mills operating in closed-circuit with hydrocyclones to control grind size, gravity concentrators to recover coarse gold, cyanide tank leaching, recovery of gold on activated carbon in the cip circuit, and a carbon elution and carbon regeneration circuit.
