• The supply to the primary crusher of a suitable mixture of RoM ore largely controls the chemical quality of the inal products. • Open pit ore is crushed via a primary gyratory crusher and two secondary cone crushers ahead of primary stockpiling. A smaller in-pit gyratory crusher is also available as required.

The screening requirements for the treatment of metal ores such as copper, zinc, manganese, etc. after the primary crushing stage can be seen as a mixture of the requirements imposed on the processing of iron ore and coal. In the field of secondary crushing, however, today‘s requirements have in many cases already shifted much further into

Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

Copper Ore crushing Process. Big copper ores are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crushing, the materials will be fed into cone crusher by belt conveyor for secondary crushing. Then, the brokenparticles will be transported to vibrating screen for classification.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Ore Crushing Operations. Outside of the Mission South Mill, trucks dump the ore into the primary crusher which reduces the rocks to 8 inches or smaller. Inside the mill, the ore is mixed with water in two rotating SAG mills which use the larger rocks and 8-inch steel balls to reduce the ore to about 10 mm or smaller.
