Copper ore processing

Copper ore introduction:

The copper ore beneficiation production line generally adopts a relatively simple process.After a period of grinding, the fineness -200 mesh accounts for about 50% to 70%,1 rough selection, 2~3 selections, 1~2 sweeps.If the particle size of the copper mineral is relatively fine, a stage grinding process may be considered.Most of the concentrating plants that deal with the porphyry ore are selected by the coarse ore re-grinding stage.The essence is the hybrid priority flotation process.


Equipment configuration: 

vibrating feeder, jaw crusher, impact crusher, ball mill, spiral classifier, magnetic separator, flotation machine, concentration barrel and dryer, etc.


Copper ore processing:

1. Broken part: The basic process of crushing the ore process. The purpose is to crush the ore to an appropriate size and is suitable for grinding a part.

2. Grinding part: The 0-12 mm copper powder sieved through the vibrating screen is evenly sent to the scoring mill for grinding and pulverizing. The ore is further processed to obtain a smaller size for the flotation separation material.

3. The ore fines ground by the ball mill enter the next process: classification.The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different.The washed and graded mineral mixture separates the magnetic material in the mixture by magnetic force and mechanical force when passing through the magnetic separator because of the different specific magnetic susceptibilities of the various minerals.The mineral particles that have been initially separated by the magnetic separator are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances.After the desired minerals are separated, the dried copper tailings can be obtained because they contain a large amount of water and are initially concentrated by a thickener and then dried by a dryer.

Remarks:The production line is mainly based on the actual material size and the customer's requirements for product granularity. According to different production site conditions, Dewo engineers can provide customers with process planning and technical support, and we can also design non-standard according to the actual installation conditions of customers and supporting components, etc., we strive to achieve a reasonable and economical production line for customers.This production line is mainly based on the crushing of ore raw materials,the post-order process and beneficiation equipment can be further consulted by Dewo technical engineers.
