Runofmine sulphide ore enters the primary gyratory crusher prior to transport to two parallel grinding circuits, each consisting of a SAG mill and a ball mill. Secondary closedcircuit grinding includes cyclone classifiers, from which the overflow feeds the flotation circuit.

Ore is crushed inpit, in three semimobile gyratory crushers. Overland conveyors feed two secondary crushers, and two mill trains each consisting of a 40 foot diameter 28 megawatt SAG mill twinned with a 44 foot length 22 megawatt Ball mill. The grinding mills are amongst the largest of their type currently operating in the world.

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

We would like to show you a description here but the site won't allow us.

Inlet head design Our inlet head improves upon what was the preeminent design for more than 30 years. The outer wall involute classifies the feed solids before they enter the inlet head. Then the feed encounters an improved vortex finder and top cover plate liner.

Magnetic Flocculators. Eriez Permanent Magnetic Flocculators aid in the separation of minute magnetic particles from liquids and slurries. Used widely in the iron and coal mining industries to speed settling of fine magnetic particles in ore slurries and heavy media slurries, they are finding new use in steel and other industries for agglomerating fine magnetic contaminants in quench water ...

The ore shoots vary in shape from the tabular to lensoidal quartz reefs to the massive to pipelike disseminated sulphide reefs (DSR). Gold mineralisation occurred as a result of the reaction between rising hot fluids and the iron rich minerals in the shear zones.

Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
