Copper Processing Equipment And Technology

Copper Processing Equipment And Technology

Process copper processing equipment is divided into three parts:

  1. Broken sections: the basic process of ore grinding process. Its purpose is crushed ore to an appropriate size suitable for the grinding part.
  2. Grinding parts: part grind ore processed further to get a smaller size for the flotation separation of materials with
  3. Flotation parts: the flotation process / upgrade copper important process. Chemicals are added to the mixer / blender, the chemical reaction.

Ore mined first by the initial jaw crusher broken, after crushing to a reasonable degree of fineness via elevator, feeder evenly into the ball mill, ball mill for ore crushing, grinding.

After grinding mill ore fines into the next process: classification. Spiral classifier with the proportion of solid particles in the liquid varies the speed of sedimentation principle, the mixture was washed ore, grading. After washing and grading in the mixture after the mineral separator, the ratio of the susceptibility of various different minerals, magnetic and mechanical forces via mixing the compound magnetic material separated. After initial separation of mineral particles in the separator is fed to the flotation machine according to the different characteristics of different drugs minerals, such as minerals and other substances to be separated from.

Construction aggregate crushing

After the minerals to be separated, because they contain large amounts of water, subject to the initial concentration of the thickener, and then dried by the dryer, and dried to obtain minerals. Copper concentrate grade of 45% can be achieved.

Two common copper beneficiation process copper ore flotation

A dyed-shaped copper ore flotation

Generally use relatively simple process, after a period of grinding fineness -200 mesh about 50% -70%, 1 roughing, 2-3 times, 1-2 times a selection of scavenging. Disseminated copper minerals such as particle size relatively small, could be considered stage grinding and separation processes. Processing bornite concentrator, mostly coarse concentrate regrinding - selection stage grinding and separation processes, and its essence is mixed - flotation process. After the first period of rough grinding, roughing, scavenging, then coarse concentrate regrinding and then get a high grade copper concentrate and a selection of pyrite concentrate. Coarse Ground degrees -200 mesh about 45% -50%, -200 mesh and then pulverized about 90% -95%.

Second, the dense copper ore flotation

Because of the dense copper ore chalcopyrite and pyrite dense symbiosis, pyrite is often activated secondary copper minerals, higher pyrite content, it is difficult to suppress, sorting difficult. Sorting process requires both get copper concentrate and concentrate. Usually after copper tailings is pyrite concentrate. If the ore gangue content of over 20% to 25%, sulfur concentrate needed to get sorted again. Dense copper ore processing, often using two stage grinding or grinding, fine grinding fineness requirements. Pharmacy amount is larger, xanthate dosage 100g / (t ore) above, lime 8 ~ 10kg (t ore) above.
