Copper ore dressing production line
Introduction of copper ore dressing production line
Copper ore dressing production line generally adopts a relatively simple process, after a period of grinding, fineness -200 mesh accounts for about 50% to 70%, 1 rough selection, 2 to 3 times selection, 1 to 2 times sweep selection. If the particle size of copper ore is relatively fine, the stage grinding process can be considered. Most of the concentrators dealing with bornite adopt the stage grinding process of regrinding and sorting of coarse concentrate, which is essentially a mixed-priority flotation process. After a period of rough grinding, rough sorting and sweeping sorting, the coarse concentrate is then re-grinding and re-sorting to obtain high grade copper concentrate and sulfur concentrate. Coarse grinding fineness -200 mesh accounts for about 45% to 50%, and regrinding fineness -200 mesh accounts for about 90% to 95%.
China is one of the countries with more copper deposits in the world. The total reserves of copper are 62.43 million tons, ranking 7th in the world. Copper rich accounts for 35% of proved reserves. Copper ore is widely distributed, in addition to Tianjin, Hong Kong, including Shanghai, Chongqing, Taiwan and other provinces (cities and districts) have output.

Flow chart of copper ore dressing production line
Copper ore processing process
Copper ore dressing process is divided into three parts:
1, crushing part: the basic process of crushing ore process. The aim is to crush the raw ore to an appropriate size suitable for grinding parts.
2, grinding part: grinding and crushing part to further process the ore to get a smaller size is to cooperate with flotation separation materials.
3, flotation part: flotation process/upgrade copper mine important process. Chemical reagents will be added to the mixer/mixer to enable the chemical reaction.
The mined ore is initially crushed by the jaw crusher, and then evenly fed into the ball mill by the elevator and feeder after crushing to a reasonable fineness. The ore is crushed and ground by the ball mill.
The fine ore grinding by the ball mill enters the next process: classification. The spiral classifier cleans and classifies the ore mixture by virtue of the principle that the specific gravity of the solid particles is different and the precipitation rate in the liquid is different. When the mineral mixture is washed and graded, the magnetic substances in the mixture are separated by magnetic and mechanical forces due to the different specific magnetization coefficients of various minerals. After the initial separation of mineral particles by magnetic separator, they are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances.
After the desired mineral is separated, because it contains a lot of water, it must be initially concentrated by the concentrator, and then dried by the dryer, you can get dry minerals. Copper powder grade reached 45%.
