Copper ore crusher and copper beneficiation plant price
XSM is a professional copper ore crusher supplier, and our copper ore crushing equipment mainly consists of jaw crusher which always as the primary crusher, jaw crusher is the commonly used as primary crushing equipment, because it can crush many kinds of material for its crushing principle of lamination protect which spare parts from being worn easily. Cone crusher and impact crusher can be used for secondary crushing, This cone crusher consisted of a cone-like chute, down which the ore passed. Inside the cone, a smaller cone-shaped crusher rotated, breaking the ore between the crusher plus the wall of the chute. If you have higher requirements on the final copper ore size, you can add the tertiary crushing equipment. VSI5X crusher and VSI crusher can be as the tertiary crushing equipment.
Copper ore beneficiation process flow
Copper ore beneficiation process is divided into three parts:
1. The broken part: the basic process of ore crushing process.Its purpose is to run of mine ore crushing to the appropriate size, suitable for grinding part.
2. Grinding parts: grinding crushed further processing ore flotation separation get smaller size is in line with material
3. The flotation: important process of copper flotation process/upgrades.Chemical reagents will be added to the mixer/mixer, the chemical reaction.
Mining ores first by the jaw crusher preliminary broken, after the broken to a reasonable fineness via elevator, feeder evenly into the ball mill, the ball mill for ore crushing, grinding.
After ball mill grinding of ore fines into the next process: classification.Spiral classifier with different proportion of solid particles in the liquid precipitation rate of different principle of mixed ore washing, grading.After cleaning and grading of the mineral mixture after magnetic separation machine,
Because of various minerals than susceptibility, through magnetic force and mechanical force will mixture of magnetic materials.After preliminary separation of magnetic separator, the mineral particles are fed into the flotation machine, according to the different mineral characteristics to join different drugs, makes separation of minerals and other substances.Desire to minerals is separated out, because it contains a lot of water, must obtain the preliminary enrichment of thickener, then through the dryer drying, drying can be minerals.Copper powder grade up to 45%.
Disseminated copper ore flotation
Generally adopt simpler process, after grinding, fineness of 200 mesh accounted for about 50% ~ 70%, one roughing and 2 ~ 3 times, 1 ~ 2 times of scavenging.Such as disseminated copper mineral particle size is fine, can consider to use stage grinding process.Processing of spot copper concentrator, mostly adopts the rough concentrate – a selection of stage grinding process, the essence of which is mixed – selective flotation process.By a coarse grinding, roughing, scavenging, and secondary then rough concentrate selected by the high grade copper concentrate and the sulphur concentrate.Coarse grinding fineness of 200 mesh accounted for about 45% ~ 50%, and the grinding fineness – 200 mesh accounted for about 90% ~ 95%.Dense copper ore density symbiosis with chalcopyrite and pyrite, pyrite is usually secondary copper mineral activation, pyrite content is higher, difficult to restrain, difficult separation.Sorting process requirements for copper concentrate and sulphur concentrate at the same time.Usually after the copper tailings is a sulphur concentrate.If in the ore gangue content more than 20% ~ 20%, still need again for sulfur concentrate separation.Deal with dense copper ore, often use two pieces of grinding or stage grinding, fine grinding fineness requirements.Dosage of reagent dosage is bigger also, xanthate above 100 g/t ore), lime above 8 ~ 10 kg undressed ore (t).
