Description
Technical Field
The invention belongs to the technical field of coal mine associated minerals, and particularly relates to a gravity separation screening system and method for coal mine associated minerals.
Background
Natural minerals often have a certain symbiotic combination and rarely appear as a pure single mineral. For example, chalcopyrite, is always symbiotic with pyrite, galena and blende. Columbite tends to co-grow with ilmenite, cassiterite, wolframite, rutile and other niobium-tantalum minerals. While ilmenite, rutile, zircon, monazite, quartz, feldspar, etc. are usually together.
When we wish to investigate a particular mineral in detail, it is first necessary to obtain as a sample an amount of a single, eutectoid mineral. To obtain a pure mineral to be studied from a complex mineral composition in nature, the mineral composition must be separated in advance to extract a pure desired mineral, which makes the mineral separation work one of the essential important steps in the whole mineral research and utilization work and is listed at the beginning of each process.
In recent years, techniques and methods for single mineral separation have been extensively developed in mineral separation scientific research in various countries. Such as magnetic beneficiation, electrostatic beneficiation, gravity (table, jigging, heavy liquor, etc.) beneficiation, wind beneficiation, flotation, dielectric beneficiation, and other chemical beneficiation, and the like.
However, the existing separation of trace and fine minerals, especially the extraction of a certain pure single mineral, has a plurality of specific problems, although the minerals can be separated by using methods such as magnetic separation, heavy liquid separation, jigging separation, electrostatic separation, electrochemical separation, dielectric separation, artificial elutriation and the like. However, for those mineral combinations that are not magnetic, conductive and have a specific gravity greater than 4, there is currently no suitable method for sorting them. This-a practical problem, has posed many difficulties for the mineral workers, even in the case of certain minerals that cannot be successfully studied.
