Kefid can provide a complete of processing equipments for processing copper ore in Chile
Recently, the world's largest copper producer - Chile's National Copper Corporation on Wednesday said the country's environmental regulatory authorities have approved the company's $ 5.4 billion worth of sulfide ore project, which is a key part of the company's plans to lift output.
It is understood that the Chile's National Copper Corporation will build a daily processing capacity of supporting 200,000 tons of copper concentrator for new projects in Chile's Atacama desert.

Copper ore is generally an aggregate of sulfide or oxide copper and other minerals. Copper ore processing technology include: crushing, grinding, beneficiation three processes. In crushing process,three-stage closed-circuit crushing are the most suitable for high hardness copper ore crushing to improve the follow-up grinding efficiency; in grinding process, two-stage grinding is efficient grinding process which can make copper more fully grinded; in beneficiation process, the more successful and new technology in recent years is bulk flotation process.
As a global strength mining,crushing production and export base, Kefid focus on copper ore processing equipment for thirty years and we can provide a complete processing technology and new equipment for Chile's copper concentrator project.
The first stage: the crushing and screening - three-stage closed circuit crushing
Chunks of copper ore was feed by vibrating feeder to jaw crusher or mobile station for primary crushing; after sieving by vibrating screen, copper ore are transferred by belt conveyor to the single-cylinder hydraulic cone crusher for secondary crushing; after secondary crushing, the materials were sent into multi-cylinder hydraulic cone crusher for fine crushing; we can adjust the fineness of the material to make it reaches 13mm or less.
The second stage: grinding
The crushed copper ore were sent to ball mill for grinding and screening by the spiral classifier.The material does not meet the requirements will be fed into the ball mill for re-grinding;
The third stage: dressing - new flotation process
The copper powder which meet the requirements was fed into the flotation machine for flotation and then fed into the dryer.Finally we obtain refined copper powder.
Kefid's mobile crusher, PEW European type jaw crusher, HST single-sylinder hydraulic cone crusher, HPT multi-cylinder hydraulic cone crusher, ball mill and other equipment have applied to many copper ore processing project, the effect is significant.
