Abstract
The present invention is the method for crystalline flake graphite purification and grinding and processing.This method is to add solid additive in raw ore, controls the granularity and the add-on of solid additive simultaneously, changes the character of grinding charge(of mill) material artificially, i.e. grindability index.Through ore grinding sorting flow process, significantly improved the regrind efficient and the crushing effect of graphite.Solid additive of the present invention can be polar silicates and alkaline-earth metal rocks and mineral, and this class additive has that the source is wide, price is low, easily separates with graphite, to advantages such as graphite products are pollution-free.The present invention compares with traditional method, and the ore grinding time can shorten 1/2 to 4/5, and the present invention is applicable to the various grinding attachments of graphite concentrate regrinding and graphite products grinding and processing.
Description
The invention belongs to the method for crystalline flake graphite purification and grinding and processing.
In the prior art, the flotation of crystalline flake graphite ore is generally adopted concentrate regrinding, is ground the floating flow process of mill of multiselect more, and obtaining grade is the medium-carbon graphite product of 80-90%.But being purified to grade from medium-carbon graphite is high-carbon graphite more than 94%, and the efficient of then regrinding is very low.For improving the problem that exists in the prior art, Romanian patent 78624.1980.4.5 has proposed a kind of method with medium-carbon graphite purification high-carbon graphite.This method is to be that 1: 1 ratio is mixed mutually with medium-carbon graphite and quartz sand (less than the 1mm level) with weight ratio, and stirs 30 minutes in liquid medium, then through hydroclone classification and carry out flotation.The shortcoming of this method is that the quartz sand consumption is big, and churning time is long, complex technical process, and the whipping device power consumption is big, serious wear, and has destroyed the big scale of graphite.(referring to " external nonmetalliferous ore " N in 1985
o.3.P
58).
Graphite ore is except the needs ore dressing and purifying, and some also needs to carry out grinding and processing to i.e.-325 orders of-43 μ m(the thin crystalline flake graphite product of ore dressing and purification) ,-10 μ m or thinner.In the prior art, with graphite disintegrating apparatus (as Raymond mill, high speed disintegrator, sand mill, micronizer mill and vibration mill etc.) commonly used both at home and abroad the crystalline flake graphite ore is pulverized, efficient is very low.
The present invention be directed to the shortcoming that exists in the prior art, a kind of crystalline flake graphite of design is regrinded and is purified and the method for grinding and processing.Use the present invention, can improve crystalline flake graphite concentrate regrinding efficient, simplify technical process, improve concentrate grade, can improve the crush efficiency of graphite ore dressing refined product simultaneously, increase the processing power of disintegrating apparatus, reduce the milling product granularity, save energy.
The present invention starts with from analyzing graphite concentrate regrinding efficient reason low and that graphite products is difficult to pulverize, broken through for a long time, graphite ore dressing both at home and abroad and graphite grinding and processing are confined to the improvement research of flotation flowsheet, flotation reagent and grinding attachment, but in the pulverizer of graphite concentrate regrinding machine and graphite products, add an amount of solid additive, change the character-grindability index of grinding charge(of mill) material, thereby improved regrinding and crushing effect of graphite significantly.The solid additive of selecting is particulate state, and the coefficient of sliding friction is big (being generally 0.5-0.9 with the coefficient of sliding friction of iron), and its adding can improve graphite regrind efficient and crushing effect greatly.Simultaneously this class additive has again that the source is wide, price is low, easily separates with graphite, to advantages such as graphite products are pollution-free.
The solid additive granularity is thicker, hardness is bigger, frictional coefficient is higher, addition the more, then graphite concentrate and graphite products grindability index better, but also more serious to the breakage of flaky graphite.The additive granularity is thinner, and addition the more then separates more difficulty with graphite, and in the separated product, additive increased the weight of mixing of graphite.
Main points of the present invention are, according to form different of graphite particle size and to the different requirements of the finished product, the granularity and the add-on of control solid additive are certain value, to obtain optimum technic index.
When carrying out crystalline flake graphite purification and grinding and processing, in raw ore, add solid additive, and the granularity and the add-on of control solid additive, raw ore is through ore grinding sorting flow process.Solid additive can be polar silicates and alkaline-earth metal rocks and mineral.As quartz, feldspar, silica, syenite, basalt, nepheline, garnet, grouan, quartz sand, sandstone, gravel, flint, dolomite, corundum, marble, limestone etc.
For the regrinding and pulverizing of thin crystalline flake graphite, the granularity of solid additive is following each grade of-16 orders, and the weight ratio of solid additive and graphite is 1: 20-1: 1.
For regrinding of big scale and mixing order graphite, the granularity of solid additive is extremely each grade of-400 orders of-30 orders, and the weight ratio of solid additive and graphite is 1: 20-1: 1.
Graphite and solid additive are at ore grinding or pulverize later separation method, can adopt methods such as flotation or electric separation according to the difference of solid additive and graphite properties.
Carrying out crystalline flake graphite according to the method for the invention purifies and grinding and processing, compare with traditional method, the ore grinding time can shorten 1/2 to 4/5, the close substantially or increase to some extent of the productive rate of big scale, and the present invention is applicable to the various grinding attachments of graphite concentrate regrinding and graphite products grinding and processing.
Regrinding and reconcentration or graphite products grinding and processing schema (seeing accompanying drawing) with reference to crystalline flake graphite of the present invention illustrate embodiment.
Embodiment 1: raw ore is-100 order medium-carbon graphites.Solid additive is quartzy, and quartz granularity is-50 orders, and the weight ratio of add-on and graphite is 1.1: 10, and ore milling concentration is 40%.The technic index contrast of the present invention and traditional method is as follows:
Embodiment 2: raw ore is for mixing the order medium-carbon graphite.Solid additive is quartzy, and quartz granularity is-200 orders, and add-on is 1.1: 10 with the ratio of graphite weight, and ore milling concentration is 40%.
The present invention and the contrast of traditional method technic index are as follows:
Embodiment 3: raw ore is+80 order medium-carbon graphites.Solid additive is quartzy, and quartz granularity is-200 orders, and add-on is 1.1: 10 with the ratio of graphite weight, and ore milling concentration is 45%.
