Copper ore crusher is as important crushing equipment during coppre ore processing, after the copper ore is baste from the open pit mining. Because the stripping ratio is different from location to location, the miner need ore crushers to crush the large copper ore rocks in to small ones, even powder. The copper ore crusher will crush the copper ore into walnut-sized pieces such as less than 25 centimeters in diameter, and the grinding mill will grind the copper ore into fine powder usually containing less than 1 percent copper.

Open-pit copper ore is hauled to the primary gyratory crusher and the discharge fed to two secondary cone crushers. Due to the dry, dusty nature of the ore and the fine crush required to optimize leach recoveries, water-flush crushers are used to perform. the tertiary crushing reduction of the ore to –12mm. Crushed ore is screened and sized to remove fines; these are treated by flotation to produce copper concentrate.

Copper Ore Crushing and Grinding Process

First the copper ore is blasted, the copper ore stone will be loaded by way of a durable truck, then be transported to the primary crusher which cuts down on the ores to 8 inches or smaller. Screens size and distribute the classified ore to a number of conveyors, like those above, for transportation for the mill for further processing.

After crushing process, the copper ore is send to ball mill for grinding. Within the ball mill, the crushed copper ore will grind the ore to about 0.2 mm with 3-inch steel balls. This copper ore slurry is finally pumped for the flotation deck. This copper ore slurry is finally pumped for the flotation deck with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.
