Copper ore is the ore exploited from copper mine. After a series of crushing, grinding and beneficiation process, the copper ore becomes a copper concentrate or copper sand with high copper content. The copper concentrate needs to be smelted and refined to become refined copper and copper products. Therefore, crushing and processing of copper ore is the first stage of copper ore beneficiation plant.
Currently, copper ore is mainly used as raw material in the metallurgical industry.
The copper ore processing and production process mainly includes three stages: crushing, grinding, and beneficiation.
During the crushing process, to follow the ‘more crushing, less grinding’ principle, three-stage closed crushing circuit is a proper method for crushing copper ores, which can complete the work of ore crushing and partial dissociation, thereby improving subsequent grinding efficiency.
The qualified crushed copper ores are fed to the grinding equipment through auxiliary equipment such as conveying equipment and feeding equipment. The copper ore, water, and steel balls in the grinding cylinder are ground and collided with each other, further reducing the ore particles.
In this stage, two stage closed grinding circuit is adopted to make the copper ore grinding more fully.
The beneficiation stage is a key stage for improving the grade of copper ore. And according to different types and properties of copper ore, we can choose different machines, such as flotation machine, magnetic separator etc.
Since copper ore has high hardness, ZENITH recommends jaw crusher and cone crusher for copper ore crushing process.
Large pieces of copper ore are uniformly fed into jaw crusher through vibrating feeder for coarse crushing. The coarse crushed copper ore particles are screened by vibrating screen and then sent to single cylinder hydraulic cone crusher for medium crushing; the medium crushed copper ore particles are sent to multi cylinder hydraulic cone crusher for fine crushing. And then the crushing process is finished.

High crushing efficiency and strong capacity
(1)High crushing efficiency: The crushing chamber adopts laminated crushing principle, the copper ore particles squeeze each other in the crushing chamber, significantly improving the crushing efficiency and the proportion of fine particles, reducing the consumption of vulnerable parts, and the products are cubical with a high content of fine particles.
(2) Strong bearing capacity: fixed main shaft, eccentric sleeve rotating around the main shaft, strong bearing capacity, large installation power, more compact structure, small size, high efficiency, and low noise.
Intelligent control and accurate regulation
(1) Siemens brand PLC and touch screen intelligent control system are adopted, featuring high reliability, convenient and intuitive operation, and complete data records.
(2) The fully automatic control system provides multiple operation modes for customers to choose from, such as manual control, constant discharge opening control, and constant power control. The automatic monitoring system can understand the operation status of the equipment in real time, which is conducive to giving full play to the performance advantages of the equipment
