Copper ore processing includes crushing, grinding and beneficiation. The selection of equipment needs to consider the properties of the ore, production capacity, energy consumption and finished product quality. Crushing is divided into three-stage closed circuit, grinding uses a two-stage one-closed process, and beneficiation uses mixed flotation. Reasonable equipment selection can improve efficiency and reduce costs.

The processing technology of copper ore mainly includes three steps: crushing, grinding and beneficiation. Among them, choosing the right crushing equipment is crucial. The following is a guide to the key processes and equipment selection for copper ore processing.

Understand copper ore crushing equipment

Crushing process

Three-stage closed-circuit crushing is the best choice for modern high-hardness copper ore crushing. It can effectively complete the crushing and dissociation of ore and improve the efficiency of subsequent grinding. The specific process is as follows:

Coarse crushing: Large pieces of copper ore are evenly fed into the jaw crusher (primary crushing) through a vibrating feeder for coarse crushing.

Medium crushing: After screening, the coarsely crushed ore is sent to a single-cylinder hydraulic cone crusher for medium crushing.

Fine crushing: The ore after medium crushing is then sent to a multi-cylinder hydraulic cone crusher for fine crushing.

Grinding process

During the grinding process, a two-stage one-closed grinding process is used to feed the screened 0-12 mm copper powder into the grinding machine to ensure more complete grinding.

Ore dressing process

In recent years, the mixed flotation process has become a successful new ore dressing method. The copper powder that meets the requirements is separated by a flotation machine and sent to a dryer to obtain copper concentrate.

Equipment selection basis

When selecting copper ore crushing equipment, the following aspects should be considered:

Ore properties: Different types of crushers are suitable for different ore properties, and the compatibility of the equipment and the ore must be ensured.

Capacity requirements: Select equipment with appropriate capacity according to production needs to meet production goals.

Energy consumption: The energy consumption of the equipment directly affects the cost. Selecting equipment with lower energy consumption can effectively reduce investment.

Finished product quality: The quality requirements of the finished product will affect the subsequent market application, so the quality of the finished product is an important factor in selecting equipment.

Common crushing equipment

Jaw crusher: suitable for coarse crushing, with high compressive strength and crushing ratio.

Cone crusher: suitable for medium and fine crushing, capable of handling high hardness materials.

Mobile crushing station: convenient and flexible, suitable for on-site operations.

By rationally selecting copper ore crushing equipment, processing efficiency can be effectively improved, costs can be reduced, and a good foundation can be laid for the subsequent utilization of copper ore.
