Abstract

The present invention relates to an industrial enriching method for sepiolite, which can be used for obtaining high-grade sepiolite from sepiolite raw ores. The sepiolite crude ores are swelled and crushed by adding water, water glass is added to the sepiolite raw ores to be dispersed at a high speed for one to two times in a dispersion machine. By means of gravity sedimentation, solid and liquid in upper suspension liquid are separated, the upper suspension liquid is dried, and sepiolite ore concentrates are obtained. The present invention can obtain high-grade sepiolite ore concentrates containing more than 90% of the sepiolite, and the recovery rate is more than 85%. From the enriching verification by using sepiolite soil in four different areas, the method is generally applied, and the method can be applied to the construction of sepiolite separating plants. The present invention has the advantages of stable quality of products, and low cost.

Description

The sepiolite beneficiation method
The present invention relates to the beneficiation method in a kind of sepiolite clay ore deposit, particularly a kind ofly add dispersant obtains the sepiolite concentrate with the gravity separation principle beneficiation method.
Sepiolite is a kind of mineral resources of rareness.Because of it has special physical and chemical performance and processing performance has the wide industrial purposes.China successively in the Leping, Jiangxi, ground such as liuyang hunan, stone Tan, Yin Tiansi, Chen Jia gulf find to have the sepiolite industrial mineral deposit of industrial value, account for 1/4th of world saving, but, fail well to be utilized always because raw ore sepiolite content is low.
Present existing sepiolite beneficiation method, as the clear 55-47937 dental of Japanese Patent Laid communique sepiolite process for purification, be heated to 90 ℃ of dispersions with polyalcohols such as hydrogen peroxide or polyethylene glycol, sedimentation separation, low-grade sepiolite is low by the refining concentrate grade that draws of this method condition, still is not so good as the method for purification of general clay.1985 in addition " Hunan geology " sepiolite paper special edition supplementary issue first phases, delivered the isolation and purification of Yonghe County, Hunan sepiolite, this method a small amount of X diffraction test standard sepiolite that is used to purify, amount is few, time is long, and the cost height can't be realized commercial scale processing.
The purpose of this method is to provide a method simple, and cost is low, constant product quality, concentrate grade height, the sepiolite beneficiation method that the rate of recovery is high.
Sepiolite beneficiation method of the present invention is that with medicament combines with mechanical means, removes accompanying impurities talcum, quartz, calcite, montmorillonite etc. from sepiolite clay, makes sepiolite obtain enrichment.
The present invention adopts mechanical means that mineral such as the close fine sepiolite of character, quartz, talcum are scatter.This mechanical means mainly uses a kind of high speed dispersor.Disperse function that sample is smashed to pieces to mineral and disperse each other, but do not destroy the sepiolite structure.
The present invention utilizes medicament that the mineral that disperse are further disperseed, and medicament is waterglass (or mixture of waterglass and a small amount of calgon).Waterglass can produce inhibitory action to calcite, talcum, quartz etc. in wholesomeness ground, and sepiolite is disperseed, and when adding waterglass, slurry mud is thinning, talcum, and quartzy, the calcite subparticle power of can relying on for support is sunk and is separated with sepiolite suspension.
The present invention proposes three kinds of beneficiation methods:
First method: adopt two sections dispersions, secondary settlement obtains the sepiolite concentrate.The sepiolite raw ore is soaked slurrying, adding medicine dispersed with stirring in dispersion machine.First section disperse water glass (or mixture of waterglass and a small amount of calgon) consumption raw ore per ton is 10~36 kilograms, stirred 2~10 minutes, for the second time adding waterglass raw ore per ton before the sedimentation after disperseing is 4.5~11.5 kilograms, added the back mixing 2~3 minutes, and carried out the sedimentation first time and remove slag.The upper strata suspension that is obtained is carried out second section dispersion again in dispersion machine, sedimentation for the second time.Suspension in dispersion machine second section disperseed 2~25 minutes, adding waterglass raw ore per ton for the third time before the sedimentation after disperseing is 4.5~11.5 kilograms, mixing 2~3 minutes, placement is spent the night, carry out the sedimentation second time and remove slag, the upper strata suspension of Huo Deing is the sepiolite concentrate slurry once more, and this concentrate slurry is carried out Separation of Solid and Liquid, drying gets the sepiolite concentrate.
Second method: adopt one section to disperse secondary settlement.Raw ore is soaked slurrying, put into dispersion machine, in dispersion machine, add waterglass (or waterglass and a small amount of sodium hexametaphosphate mixture) then, raw ore per ton is 10~36 kilograms, jitter time is 5~20 minutes, and adding waterglass raw ore per ton for the second time before the sedimentation after disperseing is 4.5~11.5 kilograms, adds the back mixing 2~3 minutes, placement is spent the night, carry out the sedimentation first time and remove slag, it is 6~13 kilograms that the upper strata suspension that is obtained is added waterglass raw ore per ton more for the third time, mixing 2~3 minutes, placement is spent the night, carry out the sedimentation second time and remove slag, the upper strata suspension of Huo Deing is concentrate slurry once more, and this concentrate slurry is carried out Separation of Solid and Liquid, drying gets the sepiolite concentrate.
The third method: adopt one section to disperse a sedimentation.Can disperse a sedimentation can obtain high-grade sepiolite concentrate through one section to the former mining increase waterglass consumption of sepiolite.Raw ore is soaked slurrying, put into dispersion machine, in dispersion machine, add waterglass (or waterglass and a small amount of sodium hexametaphosphate mixture) then, raw ore per ton is 25~53 kilograms, dispersed with stirring 2~10 minutes, adding waterglass raw ore per ton for the second time before the sedimentation after disperseing is 6~15 kilograms, dispersed with stirring 2~3 minutes, placement is spent the night, sedimentation is removed slag, and the upper strata suspension that is obtained is concentrate slurry, and this concentrate slurry is made Separation of Solid and Liquid, drying gets the sepiolite concentrate.
The present invention to the sepiolite clay raw ore by soaking slurrying in 1: 9~1: 7.Native concentration is 10~15% in the dispersion slip in dispersion machine.During sedimentation in the slip native concentration be 10~15%, the sedimentation time is more than 10 hours.
The mine tailing redispersible recovery of the present invention after to the sepiolite clay ore dressing be sepiolite wherein.
Example one
Each 1 kilogram of flat, Chen Jiawan, stone Tan, temple, silver-colored field sepiolite original soil seek pleasure, carry out respectively by soaking slurrying in 1: 9~1: 7, add 70~180 milliliters of 14.3% waterglass, disperseed 2~10 minutes in the dispersion machine high speed, add for the second time 30~80 milliliters of waterglass, mixing 2~3 minutes, placement is spent the night, and upper strata suspension was disperseed 5~20 minutes in the dispersion machine high speed again, adds 30~80 milliliters of 14.3% waterglass for the third time, mixing 2~3 minutes, placement is spent the night, sedimentation remove slag upper strata suspension concentrate slurry, concentrate slurry is carried out Separation of Solid and Liquid, drying gets the sepiolite concentrate.Concentrate X diffraction phase analysis the results are shown in Table 1.
