The rougher bulk concentrate contains 4% copper with 75% recovery. After recleaning, the final copper con-centrate produced contains at least 20% copper with 85% recovery. The plant within the Tominskii MPE produces 28 million t of porphyry copper ore per year, where the initial content of copper in the ores is 0.4%.
Crushing in Copper Production Operation. Crushing is the first size reduction stage in copper production operation; it aims to reduce the large lumps of raw materials into small particles preparing for further operation. Large raw copper ore are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
In a test performed in the Loesche test center in Germany, copper slag grinding saved 22.9% energy in an air-swept model and 34.4% energy in an overflow model [13,14].
The large copper ore is evenly sent to the jaw crusher or mobile jaw crushing station (primary crushing) by the vibrating feeder through the silo for coarse crushing. The coarsely crushed copper ore is screened by a vibrating screen, and then sent to a single-cylinder hydraulic cone crusher (middle crushing) by a belt conveyor for …

The ore crushing process includes four types: ore coarse crushing, ore medium crushing, ore fine crushing, and ore superfine crushing. Ore coarse crushing is a process of crushing ore blocks with a feeding particle size of 500–1500 mm to 125–400 mm. The maximum crushing ratio of coarse crushing is about three. The main force in …
The crushing section illustrated is designed to handle the full tonnage in approximately 8 to 16 hours thus having reserve capacity in case of expansion. COPPER ORE STORAGE. Many mills store not only the coarse ore but also the fine ore in open stockpiles using ore as the side walls and drawing the live ore from the center.

The ore is first crushed into a fine powder and mixed with water to form a slurry. Chemicals called collectors are then added to the slurry, which attach to the copper minerals and create a hydrophobic surface. Next, air is injected into the mixture, causing the copper minerals to float to the surface as a froth.
