Copper ore crushing Characteristic

Copper ore refers to ore containing copper or copper compounds. It exists mainly in the form of chalcopyrite in the natural distribution of copper ore, as well as porphyrite, chalcopyrite and azurite. In the crushing and sorting process of copper ore, after a series of processes of crushing and beneficiation, it becomes a copper concentrate or copper ore with a high copper grade. Copper concentrate needs to be refined and refined to become refined copper and copper products.

Copper ore crushing Process

The copper ore crushing and sorting process mainly includes four processes: copper ore crushing, grinding, beneficiation and copper fine powder drying. In the copper ore crushing process, the use of three-stage closed-circuit crushing is a relatively mature copper ore crushing process, which can complete copper ore crushing and partial waste ore dissociation, effectively improve the subsequent grinding efficiency; in the grinding process, the ball mill and The second stage and one closed grinding of the classifier combination; the mixed flotation process is mainly used in the beneficiation process.

The first paragraph: copper ore crushing section

In combination with the current situation of domestic copper ore raw materials, the principle of “breaking more and less grinding” is broken in the design of the crushing section process. Mainly adopts: the process of multi-stage crushing of jaw crusher + coarse crusher crusher + fine crusher crusher + high pressure roller mill. When the traditional crushing equipment is used for crushing copper ore, most of them can only be broken to 0-12mm. The Dahongli machine can reduce the copper ore to 0-5mm by using the optimized design scheme, effectively reducing the subsequent grinding. Cost and time.

Second paragraph: grinding section

The 0-5mm copper ore material crushed by the crushing section enters the ball mill for re-grinding, and has reached the requirements of the subsequent process materials. The ball mill usually works with the classifier to form a grinding and grading unit. The ball mill grinds the material to be treated, and the classifier divides the ground product into qualified materials and unqualified materials. Unqualified products are returned to the ball mill for regrind to improve the grinding process. The grinding operation entered by the classifier and the graded return sand constitutes a grinding closed section. The grading work may be pre-grading, checking grading, controlling grading, or both. The grinding machine can be used in the form of rod grinding and ball milling in the grinding process.

Third paragraph: mixed flotation section

In view of the fact that the copper ore contains different genus components, it can be selected by a combination of multiple beneficiation processes. Use a wide range of gradient magnetic separation, gravity selection, flotation, and the like.

Fourth paragraph: drying section

The copper powder after flotation is sent to the dryer, and the drying process mainly removes the moisture content of the selected copper powder in the beneficiation process to obtain high-quality copper fine powder.
