Copper ore dressing production line

Copper ore dressing production line generally use a relatively simple process, after a period of grinding, fineness -200 mesh about 50% to 70%, 1 rough selection, 2 to 3 times selected, 1 to 2 times the election. Such as copper mineral dip particle size is relatively small, may consider the use of stage grinding process. Most of the concentrates used to deal with spot copper mines are re-grounded - the selected stage grinding process, which is essentially a mixed-priority flotation process.

【Applicable materials】: copper ore

【Application】: copper ore dressing

【Equipment configuration】: vibration feeder, jaw crusher, impact crusher, ball mill, spiral classifier, magnetic separator, flotation machine, concentrated barrels and dryer

Copper ore dressing production line Details:

Copper reserves China is one of the world's largest copper mines. Total reserves of copper 62.43 million tons, ranking seventh in the world. Proved reserves of copper in the copper accounted for 35%. Copper is widely distributed, in addition to Tianjin, Hong Kong, including Shanghai, Chongqing, Taiwan, including the provinces (cities, districts) are output.

Copper ore dressing production line generally use a relatively simple process, after a period of grinding, fineness -200 mesh about 50% to 70%, 1 rough selection, 2 to 3 times selected, 1 to 2 times the election. Such as copper mineral dip particle size is relatively small, may consider the use of stage grinding process. Most of the concentrates used to deal with spot copper mines are re-grounded - the selected stage grinding process, which is essentially a mixed-priority flotation process. First by a rough grinding, rough selection, sweep, and then re-grinding and then get the coarse concentrate high-grade copper concentrate and sulfur concentrate. Coarse grinding grade -200 mesh accounted for about 45% to 50%, and then grinding degree -200 mesh accounted for about 90% to 95%.

Copper ore dressing process:

Copper ore dressing process is divided into three parts:

1. The basic process of crushing the ore process. Its purpose is to crush the ore into the appropriate size, suitable for grinding part.

2. Grinding part: grinding crushed part of the further processing of ore to get smaller size is to match the flotation separation material

3. Flotation part: flotation process / upgrade copper mine an important process. Chemical reagents will be added to the mixer / mixer to allow chemical reactions.

The ore is first crushed by the jaw crusher, broken into a reasonable fineness after the hoist, the feeder even into the ball mill, by the ball mill on the ore crushing, grinding.

Through the ball mill grinding ore fines into the next process: grading. Spiral classifier with the proportion of solid particles in the liquid in the different speed of the principle of precipitation, the ore mixture was washed, graded. After the cleaning and grading of the mineral mixture through the magnetic separator, due to the different than the magnetic properties of various minerals, through the magnetic and mechanical forces to separate the magnetic material in the mixture. After the initial separation of the magnetic separator after the mineral particles were sent to the flotation machine, according to different mineral properties by adding different drugs, so that the required minerals and other substances separated.

After the required minerals are separated, because it contains a lot of water, subject to the initial concentration of the concentrator, and then dried by the dryer, you can get dry minerals. Copper powder grade reached 45%.
