Background technology
Graphite is a kind of very important nonmetallic mineral material, and it has the good characteristics such as high temperature resistant, anti-thermal shock, high chemical stability, pyro-conductivity and lubricity, therefore is widely used in the industrial departments such as machinery, metallurgy, refractory material, chemical industry, Aero-Space.Along with the development of science and technology, the graphite consumption constantly increases in the world wide, and people no longer are satisfied with the demand to flaky graphite, and the development and utilization of thin crystalline flake graphite is just come into one's own.
The method for separating of domestic thin crystalline flake graphite has three kinds of methods such as electrical concentration, gravity separation method, floatation at present.
Electrical concentration: graphite has good electric conductivity, and gangue mineral such as feldspar, quartzy, the electric conductivity such as pyrite are relatively poor, utilize this characteristics, be easy to a graphite and other mineral separately, this method at home thin crystalline flake graphite sorting aspect was once used, because the reasons such as its production capacity is little, and efficient is low are not promoted.
Gravity separation method: gravity treatment is carried out sorting according to valuable mineral is different with gangue proportion, paragenous mineral can be divided into by proportion in the graphite ore: 1) heavy mineral (proportion＞3.32), main has: secondly pyrite, magnetic iron ore, limonite, zoisite etc. are aspidelite, zircon, white titanium ore, monazite, scheelite etc.; 2) mediumly mainly contain diopside, the tremolite than heavy mineral (2.9～3.32), apatite etc. is arranged once in a while; 3) light mineral (proportion＜2.9) mainly contains graphite and its paragenous mineral.Therefore can adopt gravity separation method according to the difference on the proportion, heavy mineral is separated, obtain take graphite as main rough concentrate.This method at home thin crystalline flake graphite sorting aspect was also once used, but was not promoted because the rough concentrate grade is lower.
The method for separating that domestic thin crystalline flake graphite is commonly used at present is floatation.The general technology that adopts is: graphite ore → roughly grind → roughly select, once purging selection → rough concentrate regrind for five times, seven times selected.Adopt this technique flotation graphite, final products graphite concentrate grade is low, and the rate of recovery is low.In the selected capital equipment: ball mill grinds graphite with hitting power between steel ball and the steel ball, is unfavorable for the sorting of large scale; The flotation device device efficiency is low, energy consumption is high.
Comprehensively estimate according to interrelated data, the thin crystalline flake graphite mineral resources amount of China can reach 300,000,000 tons, in order effectively to make good use of these mine resources; allow it turn waste into wealth; thereby reach both energy-saving and emission-reduction, the purpose of protection of the environment again is necessary to design a kind of device combination of thin crystalline flake graphite floatation process.
