In modern industry and daily life, copper has a wide range of application and demand. It has an important and irreplaceable position in electric, marine, aviation, communication, petrochemicals, household appliances, high-energy physics, metallurgy, etc.
Types of copper ore:
composition of cooper ore is very complex, including chalcocite, chalcopyrite, azurite, tetrahedrite, malachite, etc. Different beneficiation process is designed according to different ore. Even if the same type of ore in different mining plant, the beneficiation process is also different. According to the properties of different ore, we will choose suitable beneficiation process.
The beneficiation methods and quality requirements of copper ore:
Flotation is main method of cooper ore beneficiation; some are also using with magnetic separation, gravity separation and wet smelting, etc.To choose the right method of beneficiation, we should study the components and structure of copper ore, and identify the type (natural and industrial) of copper, and know about the content of refractory minerals in the ore and its general distribution, etc.According to the different proportion of copper oxide and copper sulfide, The natural copper ore can be divided into sulfide ore (containing copper oxide below 10%), mixed ore (containing copper oxide, 10 ~ 30%) and oxidized ore (containing copper oxide more than 30%).
The common methods of beneficiation for different types of copper ore, as below:
1.Beneficiation of single sulfide copper ore: Generally, it adopts flotaion.
2.Beneficiation of polymetallic sulfide ores. Generally, according to the different processing technology of main components and the characteristics, we will adopts mixed flotation, preferred flotation, mixed and preferred flotation, flotation and gravity combined beneficiation, flotation and magnetic separation combined beneficiation, flotation and wet smelting combined method.
3.Mixed ore beneficiation.Generally,we will adopt flotation beneficiation. It can be processed separately, or together with the sulfide ore. And also can adopt flotation and wet smelting combined processing, that is to say, copper concentrate selected firstly by flotation, the tailings after flotation are processed in wet smelting.
4. Oxidation ore beneficiation. Generally, we adopt flotation and wet smelting combined method or separation and flotation combined processing. we adopt wet smelting processing to deal with ore which has large content of cooper oxide.
The process of copper ore beneficiation production line designed by our company is as follows:
Mining ores first by the jaw crusher for preliminary broken, in broken to a reasonable fineness through ascension machine, after to mine machine uniform into ball mill, ball mill by crushing, grinding of ore.
After grinding ball mill of ore materials into the next procedure and: grading. spiral classifier with different proportion of solid particles in the liquid and the speed of the precipitation different principle of minerals, the mixture to wash, grading. After a wash and classification of the mineral mixture after magnetic separation unit.
Because of various minerals than magnetized coefficient of different magnetic force and, by mechanical force will mixture of magnetic material separated. After magnetic separators preliminary after the separation in mineral grains was sent into the flotation machine, according to different mineral properties of different drugs, make to the minerals and other material separation open.
Desire to minerals is isolated, because its a lot of moisture, must be approved by the initial concentration concentrating machine, then through the dryer drying, you will get dry minerals. Copper fine powder grade reached 45%.
