Copper ore beneficiation process

I. Ore Preparation
1. Ore Mining: Copper ore is typically mined from open-pit or underground mines.
2. Crushing: Large copper ore is first crushed in a crusher. The crushing process is typically divided into three stages: coarse, medium, and fine crushing. The goal is to reduce the ore to a suitable particle size for subsequent grinding.
Coarse Crushing: A jaw crusher or gyratory crusher is used to reduce the ore to a larger size.
Secondary Crushing: A cone crusher is used to further crush the ore.
Fine Crushing: A fine crusher or cone crusher is used to reduce the ore to a particle size suitable for grinding.
3. Screening: The crushed ore is screened using a vibrating screen to separate particles of varying particle sizes for subsequent processing.

II. Grinding
The purpose of grinding is to further finely grind the crushed ore until the individual particles are dissociated, allowing for the thorough separation of useful minerals from gangue minerals.
Grinding Equipment: Commonly used grinding equipment includes ball mills, rod mills, and autogenous mills. During the grinding process, it’s necessary to control the grinding concentration, add an appropriate amount of grinding media (such as steel balls and steel rods), and adjust the grinding time to achieve the appropriate grinding fineness.

III. Ore Beneficiation
Copper ore beneficiation methods vary, including flotation, magnetic separation, gravity separation, chemical separation, and combined beneficiation. Select the appropriate beneficiation process based on your needs (for details, please refer to https://www.sbintech.com/common-beneficiation-methods-for-copper-ore.html).

IV. Concentrate Processing
1. Dehydration: Removes moisture from the concentrate through concentration, filtration, and drying to facilitate subsequent smelting and processing.
Concentration: This is performed in a concentrator.
Filtration: This is typically performed on a filter.
Drying: This is performed in a dryer.
2. Tailings Treatment: Appropriately handle the tailings generated during flotation, including storage in a tailings pond, re-concentration, and comprehensive tailings utilization. Among them, tailings pond storage is a more common treatment method, while tailings re-selection and comprehensive utilization of tailings help to improve resource utilization and reduce environmental pollution.
