This customer comes from Mongolia. Due to the limits in geolocation and policies, this customer needs to depend on import for acquiring excellent copper-molybdenum ore processing machines. So, this customer builds a long-term cooperation with our company. He bought machines like SP flotation machine, Ф2700×4500 ball mill, etc. In order to expand the production, he decides to purchase a whole production plant at this time. Through a series of careful investigation, our specialists and engineers design a 300t/h copper-molybdenum ore beneficiation plant and now it has been working for a long time. And our customer’s benefit increases a lot.
Graphite ore can be divided into crystalline graphite, flake graphite and graphite ore with a variety of gangue. The graphite ore beneficiation process is mainly for the graphite ore with different crystal forms, such as graphite ore, pyrite or mica. It adopts multi-stage grinding multi-stage flotation and re-election flotation combined with two beneficiation processes. Because crystalline graphite has natural floatability, flake graphite has good floatability. Therefore, for these two kinds of graphite ore, hanfa usually adopts multi-stage grinding multi-stage flotation method for beneficiation. The reason why the multi-grinding and multi-floating method should be used is to protect the graphite scales, ensure that the scales are not damaged, and ensure that the quality of the concentrate meets the requirements. In the multi-stage flotation process, the application of flotation reagents: collectors should use diesel, heavy oil, kerosene, sulfuric acid, phenols, etc.; foaming agents should use No. 2 oil, No. 4 oil, butyl ether oil and Ether alcohol and the like.
The beneficiation equipment used in multi-stage grinding multi-stage flotation method includes: crushing mostly using jaw crusher for coarse crushing, hammer crusher and cone crusher for medium crushing; grinding ball mill and lattice ball mill are usually used in grinding stage; The flotation equipment commonly used in the selection stage includes JJF flotation machine, XCF flotation machine and XJB rod flotation machine; in the dehydration stage, we will use hydrocyclones and belt filters.
Through vibrating feeder, large raw ores are continuously fed into PE jaw crusher for primary crushing, then into PEX jaw crusher for secondary crushing, after into circular vibrating screen for screening work. For those larger crushed ores, they would be delivered back to PEX jaw crusher again for continuous crushing. While, for those qualified ones, they will enter into storage bin through conveyors.
Grinding and classifying stage
Crushed copper-molybdenum ores in storage bin are conveyed into ball mill for being ground. The ground powders will enter into spiral classifier for being classified and washed.
Flotation separation stage
For those qualified copper-molybdenum ore powders, they are conveyed into mixer barrel and added with certain amount of drugs. After the complete mixing and agitation, these powders will enter into flotation machine for dressing work.
Copper-molybdenum ore concentrates produced after the flotation stage are relatively wet. So, they need to subside in thickener and are dried in dryer. Finally, dried finished concentrates will be produced.
