Copper ore refers to the general term for available copper-containing natural mineral aggregates. Copper ore is generally an aggregate composed of copper sulfide or oxide and other minerals, which react with sulfuric acid to form blue-green copper sulfate. Copper industrial minerals include natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. There are more than 280 kinds of copper-bearing minerals that have been discovered, and only 16 are the main ones. Chalcopyrite (compounds of copper, sulfur, and iron) is mainly used for mining, followed by chalcocite and bornite.Iron exists in nature in the form of compounds, especially in the form of iron oxide. Several common iron ores are magnetite, hematite, limonite, siderite, and so on.
The world's copper ore resources are mainly concentrated in Chile, Australia, Peru, the United States, Mexico, Russia, and other countries, among which Chile is the country with the richest copper ore resources in the world.
Copper ore crusher is mainly used to crush copper ore. Copper ore is the main raw material for processing refined copper and copper products. Copper ore is gradually separated by crushing and screening, grinding, magnetic separation, drying, and other procedures Produce copper concentrate.
Recommended crushing equipment: jaw crusher for coarse crushing and hydraulic cone crusher for medium and fine crushing. This is mainly due to the relatively high hardness of copper ore. The biggest advantage of a hydraulic cone crusher is that it can crush materials with medium and fine hardness.
Recommended grinding equipment: Ball mill is a grinding machine specially developed for metal beneficiation production. It has a good abrasive shape, high fineness, and high output, and is widely used in mineral processing, building materials, and other fields.
The mined copper-bearing ore is firstly crushed by the jaw crusher, and then the secondary or fine crushing operation is carried out by the hydraulic cone crusher. After being crushed to a reasonable fineness, it is evenly sent to the wet ball mill through the elevator and the ore feeder. The ball mill crushes and grinds the ore.
The copper ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the copper ore mixture by virtue of the principle that the specific gravity of the solid particles is different and the sedimentation speed in the liquid is different. The classified copper ore enters the flotation machine for roughing, sweeping, and beneficiation. The selected wet concentrate is shrunk by the concentrator and then dried by the dryer to obtain copper concentrate.
The copper ore beneficiation process is composed of jaw crusher, ball mill, classifier, mixing tank, flotation machine, concentrator and dryer, and other main equipment, which can form a complete beneficiation machine with ore feeder, hoist, and belt conveyor production line. The production line has the advantages of high output, low energy consumption, high processing capacity, and reasonable economy.
Jaw Crusher, Cone Crusher: To crush the ore, so that the useful minerals and gangue minerals can be dissociated individually.
Vibrating screen: Divide the mixed material into different grades according to the particle size, sort out the products with qualified particle size, avoid over-crushing of ore, and improve the productivity of the crusher.
Ball mill: for ore crushing to make the ore reach a finer particle size.
Spiral Classifier: Separating qualified products in time to avoid over-grinding, and at the same time separating unqualified coarse sand and returning it for re-grinding.
Hydrocyclone: separates qualified products in time, and also has the function of concentration.
Flotation machine: Aerate and stir the ore pulp, so that the ore particles that have been affected by the collector on the surface adhere to the air bubbles, and scrape them out with a scraper to obtain concentrate.
Thickener: Precipitate and concentrate the pulp, so that the thinner pulp is separated into clarified liquid and pulped.
Filter: remove most of the capillary moisture in the material.
In addition, there are some auxiliary equipment, such as an electric vibration feeder, belt conveyor, mixing tank, ore bin, sand pump, pump pool, motor, etc.
Iron ore crusher can be widely used in the metallurgical industry, construction industry, road construction industry, chemical industry, and phosphate industry, suitable for crushing hard and medium hard ores and rocks (such as iron ore, copper ore, limestone, quartz, granite, sandstone, etc.).
