Technological scheme for crushing and processing copper ore.

The development of the manufacturing industry is inextricably linked to the use of copper. According to a report published by the Copper Development Association (CDA), since the beginning of the 21st century, copper has been widely used in the electrical and electronics industries, mainly in the production of electronic products such as mobile phones and computers, accounting for more than half of total consumption. However, in our country, most of the copper ore is imported from abroad, and domestic investors rarely invest in copper ore processing. Why is this happening? On the one hand, copper ore reserves in our country are indeed limited, but the main reason is the lack of knowledge of this industry among investors. Shibang Group, as a domestic supplier of mineral crushing solutions, has been involved in copper ore processing technologies for thirty years, and we will reveal to you the secrets of copper ore processing technologies and solutions.

Overview of copper ore processing technology

The process of copper ore processing and production includes three main stages: crushing, grinding, and beneficiation. Modern methods of copper ore crushing use a three-stage closed-circuit crushing system. This method not only provides crushing and partial liberation of the ore, but also increases the efficiency of subsequent grinding. In the grinding process, a two-stage closed-circuit grinding process allows for more thorough grinding of the copper ore. In the beneficiation process, mixed flotation is one of the most successful new processes in recent years.

Stage 1: Crushing and Screening - Three-stage closed-circuit crushing

Large pieces of copper ore are uniformly fed into a jaw crusher or mobile crushing plant for coarse crushing using a vibrating feeder.

The coarsely crushed copper ore is screened on a vibrating screen and then transported by a belt conveyor to a single-cylinder hydraulic cone crusher for medium crushing.

The material after medium crushing is sent to a multi-cylinder hydraulic cone crusher for fine crushing.

Stage 2: Grinding - Two-stage closed-circuit grinding

Copper ore of 0-12 mm fraction, screened on a vibrating screen, is uniformly fed into a ball mill for grinding.

The ground material is screened by a spiral classifier, and the material that does not meet the requirements is returned to the ball mill for further grinding.

Stage 3: Enrichment - Mixed Flotation Process

The prepared copper ore powder is sent to a flotation machine for mixed flotation.

The floated copper ore powder is sent to a dryer for drying, resulting in copper concentrate. Main equipment for copper ore processing:

C6X series jaw crusher: used for primary crushing, processing large pieces of ore.

HST hydraulic cone crusher: suitable for secondary crushing, processing harder ores with a high crushing ratio.

HPT hydraulic cone crusher: used for fine crushing, characterized by high efficiency and energy saving.

VSI6X sand making machine: used for sand production, improving the quality of sand and gravel.

Thanks to this scientifically sound processing technology and modern equipment configuration, the crushing, grinding, and enrichment of copper ore can be carried out efficiently and stably, meeting the requirements of subsequent smelting and improving resource utilization efficiency.
