Coal mine associated mineral product gravity separation screening system and method

Abstract

The invention discloses a coal mine associated mineral product gravity separation screening system and method. The coal mine associated mineral product gravity separation screening system comprises a mineral product smashing device, a sorting device and a gravity separation device. The mineral product smashing device is used for smashing collected mineral products, the sorting device is used for sorting the mineral products smashed by the mineral product smashing device, and the gravity separation device is used for separating coal mines and associated mines in the coal mine products; the mineral product smashing device is connected with a drying module, and the drying module mainly comprises a drying oven; the sorting device is connected with a transportation module, and the transportation module is used for connecting the mineral product smashing device and the sorting device; and the gravity separation device is connected with a detection module. The coal mine is subjected to primary separation by the coal mine associated mineral product gravity separation screening system, light soil scraps and dust are separated out, impurities entering subsequent gravity separation are reduced, the gravity separation accuracy is improved, and meanwhile the utilization rate of the coal mine associated mines is increased.

Description

technical field [0001] The invention belongs to the technical field of coal mine associated mines, and in particular relates to a gravity separation and screening system and method for coal mine associated mines. Background technique [0002] Minerals in nature often have a certain symbiotic combination, and rarely appear as a pure single mineral. For example, chalcopyrite: always coexists with pyrite, galena, and sphalerite. Niobite: It often coexists with ilmenite, cassiterite, wolframite, rutile and other niobium and tantalum minerals. And ilmenite, rutile, zircon, monazite, quartz, feldspar, etc. are usually together. [0003] When we want to conduct detailed research on a certain mineral, we must first obtain a certain amount of pure single mineral as a sample. In order to obtain a certain pure mineral from the complex mineral combination in nature, it is necessary to separate the mineral combination in advance to extract a certain pure required mineral, which makes ...

AI Technical Summary

Problems solved by technology

[0005] However, there are still many specific problems in the separation of trace and fine-grained minerals, especially the extraction of a certain pure single mineral. Although magnetic separation, heavy liquid separation, jigging separation, electrostatic separation, Electrochemical separation, dielectric separation and manual elutriation to separate minerals

However, there is still no suitable method for sorting those mineral combinations that are non-magnetic, conductive, and have a specific gravity greater than 4.

These practical problems have caused many difficulties for mineral workers, and even some minerals cannot be successfully studied
