The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to 1.3 cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.

How to Process Copper Ore: Beneficiation Methods and Equipment
Copper ore dressing equipment 1. Flotation machine Flotation is the most widely used method in copper mine production. The copper ore pulp is stirred and aerated, and the ore particles adhere to the s under the action of various flotation agents. The s rise to form a mineralized layer, which is scraped or overflowed by the scraper.
SIMULATION OF ORE DRESSING PLANTS
Four fundamental concepts underlie the construction of an ore dressing plant simulator. * Ore dressing plants are collections of unit operations connected by process flow streams that transmit material from one unit to the next. The flow of materials is directed by the flowsheet structure.
