Chile is a country very rich in mineral resources. Many mineral reserves largest in the world. Especially copper resources, ranking first in the world. Chile is also an important mineral producing countries and mineral exporting countries, the world’s copper, lithium and other minerals market has an important influence in the world.
With its mining policy in recent years, some major changes, particularly the establishment of a mineral royalty regime, a substantial increase taxes in the mining sector, the mining investment environment had a greater impact crusher pf1315, hydraulic cone cursher or hcs series cone crusher, receiving much attention from the international mining industry.
Advanced technological process of Copper mine mining:
Copper ores first by the jaw crusher preliminary broken, after the broken to a reasonable fineness via elevator, feeder evenly into the ball mill, the ball mill for ore crushing, grinding.
After ball mill grinding of ore fines into the next process: classification.Spiral classifier with different proportion of solid particles in the liquid precipitation rate of different principle of mixed ore washing, grading.After the minerals to be separated, because they contain large amounts of water，so they must be initially concentrated by the concentrator, and then dried by the dryer, and dried to obtain minerals. Finally, copper concentrate grade of 45%.
