Copper ore processing is an industrial process of extracting copper metal from raw ore using physical and chemical methods. Modern copper ore production lines mainly adopt an advanced technical route that combines three-stage closed-circuit crushing, two-stage one-closed grinding and flotation technology.

1. Copper ore processing process

Crushing stage: adopt a three-stage closed-circuit crushing process. Large pieces of copper ore are first coarsely crushed by a jaw crusher, and then enter a cone crusher to complete medium and fine crushing, and finally obtain a crushed product with a particle size of 0-12mm. Liming Heavy Industry's HPT hydraulic cone crusher performs well in this link.

Grinding stage: adopt a two-stage one-closed-circuit system. The crushed material is ground by a ball mill and graded by a spiral classifier. Unqualified products are returned for further grinding to ensure that the copper minerals are fully dissociated.

Sorting stage: Apply a new flotation process. The qualified ore powder is sent to the flotation machine for mixed flotation, and the copper and sulfur are separated by reagent adjustment to finally obtain copper concentrate.

2. Core processing equipment

The crushing process uses C6X series jaw crushers, HST single-cylinder and HPT multi-cylinder hydraulic cone crushers; grinding uses vertical mills or ball mills; the flotation system is equipped with special flotation machines and grading equipment.

3. Technical advantages

The three-stage crushing process has low energy consumption and high efficiency

The two-stage one-closed grinding ensures full dissociation of minerals

The new flotation process has high recovery rate and good grade

High degree of automation and low operating cost

Take the 5,000 tons/day copper ore dressing project implemented by Liming Heavy Industry in Jiangmen, Guangdong as an example. The production line has been running stably since it was put into production, providing high-quality copper concentrate raw materials for local smelting companies.

With the continuous growth of demand for copper resources, copper ore processing production lines using modern equipment and processes will become an important support for the development of the industry. In the future, more energy-saving and efficient copper ore processing technologies will continue to emerge.
