Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago.
Copper mineral is widespread all over the world, large copper deposits are found in Chile, United States, Mexico, Indonesia, Peru, Sweden etc. According to globally developing trends, copper is a main and prominent source of energy.
Currently, most of the available copper appears to be distributed over large areas, mixed with mineralizedmaterials and rock.There are a great number of compounds that contain copper, which are mainly classified in two groups: These are the porphyry deposits, which could only be exploited when metallurgical skills to separate and recover the metal were developed.
Due to its importance in human life, copper production technology has been highly developed. There are several different technics involved in copper production process. Mainly copper goes through different stages and degrees of refinement, to a lesser extent the byproducts such as molybdenum, sulfuric acid and precious metals that come with copper in the ore. Following are main stages in copper production process, after these processing operations, copper concentrates will be obtained.
Leaching or Smelting
Crushing is the first size reduction stage in copper production operation; it aims to reduce the large lumps of raw materials into small particles preparing for further operation. Large raw copper ore are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After primary crushing, the material will transferred to cone crusher by belt conveyor for secondary crushing; the crushed copper ore stone will then transferred to vibrating screen for separating.
After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to cone crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement. SBM is specialized in manufacture crushing machine. We provide various types of quarry and processing crushing plant for sale.
With this degree of hardness, it was necessary to restructure the crushing stage to reduce the top size of feed material to the grinding process, and increase the treatment flow of the plant. Two alternatives copper ore crushing production line were proposed and tested on the plant site. These were:
Primary gyratory crusher, secondary impact crusher, tertiary cone crusher, vibrating screen etc.
Primary jaw crusher, secondary cone crusher, tertiary VSI crusher, belt conveyor, vibrating screen etc.
In copper processing operation, many copper crushing processes are operated by mobile crusher machine. The innovative design of mobile copper crusher machine offers owners the highest possible fatigue strength, truly mobility and flexibility, excellent reliability and numerous mounting possibilities.
Due to its hardness, the copper ore may require as much as a tertiary crushing.Jaw crusher, impact crusher, or gyratory crushers are usually used for initial reduction. The primary crushed stone that is too large to pass through the top deck of the vibrating screen is processed in the secondary crusher, such as impact crusher or cone crusher. Tertiary crushing is usually performed using cone crushers or other types of impact crushers.Copper crushing requires high quality crusher machine for producing even particle size. Some crushing operation will apply VSI crusher for copper processing.
Spiral classifiers are designed to provide the most effective pool area and overflow velocity requirements.
Vertical Roller Mill are advanced mill equipment adopting top grinding technology applied widely in grinding non-flammable and non-explosive materials.
Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa.
SBM has released the K series portable crushing and screening plants, which contain 72 models that fit various crushing work in metal mines, building aggregates and solid waste treatment fields.
Mobile cone crusher is suitable for secondary and tertiary crushing in direct feed applications.
