Abstract
A mud-removing technique for pelitic glauberite features that said pelitic glauberite ore is separated by hot natural or manual mining water for underground ore bed and dipping liquid of tailings and based on gravity settling principle a multi-stage combination of dynamic and static settlements is used to remove mud impurities. High-purity and high-concentration solution of sodium sulfate is cheaply prepared, which may be used to prepare glauber salt.
Description
The present invention is a kind of desliming impurity removing technology of shale type glauberite.
The invention belongs to mining industry-chemical technology field.
Shale type glauberite, because of shale (clay mineral) content height, general about 10% to 50%, ore molten from after, the shale particle is difficult to separate from suspension, the cost of perhaps separating is too high, and cause no industrial economy meaning, make this Mineral resources fail so far to be exploited.
For glauberite, " in the technical process that chemical technique handbook (Science and Technology of Shanghai press,, Jiang Tiqian chief editor in 1992) is introduced, the way of " filtration " is adopted in the desliming removal of impurities.But existing filter plant only is suitable for chiltern type raw material, is helpless to the fine particle in the shale type raw material.The particulate shale enters filtrate, and product purity is reduced.
This handbook is also introduced the artificial saltcake in salt pan is washed mud device washing desliming with multilayer method for the 239th page.The artificial saltcake in salt pan is different with the natural solid mineral raw material, and silt content is low, is easy to washing and removes.
(Λ .B. is assorted to thank to also baby by the former Soviet Union works of people such as the Yuncheng salinization Li Zhen sage of office translation " character of sodium sulfate and manufacturing) ", B.B. point out the Li Yanuofu that helps work), (saltcake is more than 75% for the glassy saltcake of bottom, Ku Chuke salt lake (being positioned at the northern and Russian boundary of Kazakhstan), sludge is below 10%), thin saltcake (sludge 10-50%), saltcake mud (sludge is more than 50%), because of the shale index height, " brought difficulty for industrial utilization; cause thus, these mineral reserve are not exploited as yet at present ".
Do not see the report of shale type saltcake ore deposit development and use in the domestic and foreign literature as yet.Some shale type saltcake producing regions of China, in the process of reconnoitring, relevant department once did the desliming removal of impurities test of laboratory-scale, attempt to remove shale with filtration way or plain sedimentation way, select because of equipment eventually and sport technique segment on obstacle, or imperfection, and can't be advanced into the industrial application stage.Several little factories that glauberite resources district, basin, Xining, Qinghai Province successively sets up according to laboratory technique all close down all because of the desliming technology does not pass a test.
The purpose of this invention is to provide a kind of reduced investment, product cost is low.Easy handling, can obtain the heavy industrial technology scheme that combines clearly and remove mud impurity of multistage sound attitude of high-purity high-concentration metabisulfite solution, thereby flood tide (only the sodium sulfate reserves verified of basin, Xining just reach 2,000,000,000 tons, about 10,000,000,000 tons of prospective reserves) shale type glauberite is developed.
Technical scheme of the present invention is:
Technical process (accompanying drawing):
Ore enters steel basin (tube) after pulverizing (can ball milling), adding simultaneously that 60-90 ℃ water and/or the thick nitre liquid of unsaturation stirs is ore pulp.These thick nitre liquid derive from underground ore bed (natural stripping or artificial stripping), perhaps also derive from tailings washing lotion etc.Ore pulp goes out temperature should remain on 35-50 ℃, should be sodium sulfate (Na
2SO
4) near saturated solution.Because the not molten breeze of small part can flow out with ore pulp, its dissolving in follow-up flow process can make ore pulp reach capacity or supersaturation.
The reason that underground ore bed hydromining liquid can not directly be utilized is, the not high enough (Na of concentration
2SO
4Content 10-25%), contain the particulate shale.But go to molten ore deposit with it, and heavy clear in follow-up flow process, can not only obtain high-purity high-concentration nitre liquid, also can reduce the ore extraction amount, and reduce the tailings quantity discharged.
If tailings washing lotion concentration is not high, also can introduce the underground ore bed hydromining that carries out.
Enter thick deep gouge from the effusive ore pulp of steel basin (tube).Thick deep gouge is a container that can hold the ore pulp sluggish flow, and worm conveyor can be installed in the bottom of groove.Ore pulp is in the sluggish flow process, and coarse grain impurity (comprising walk) wherein precipitates under action of gravity, and available worm conveyor or other instruments are removed.
After adding flocculation agent, enter nothing rake thickners or other concentrated machinery of 2-a plurality of reductions successively through slightly heavy ore pulp, ore pulp continuous flow therein is clearly heavy, can make purer nitre liquid.
Thick nitre liquid enters static subsider (being called for short quiet deep gouge) after adding cleaner (for removing calcium, magnesium, the iron plasma in the nitre liquid).Quiet deep gouge is rectangle or other shapes of containers, and the bottom is equipped with a plurality of awl buckets that are beneficial to the discharging of mud impurity.Its quantity is no less than 3.About 3-6 of the time that liquid leaves standstill in groove hour.The size of quiet deep gouge and quantity should be able to guarantee that the thick nitre liquid from last process is taken turns " storage ", heavy clear and discharge incessantly.Be deposited in mud impurity discharging regularly from the awl bucket of bottom land.
All need strict insulation from slightly sinking to quiet heavy all equipment, guarantee that nitre liquid can crystallization in static subsider.
With refining nitre liquid is raw material, can be processed as the Chemicals of sodium sulfate series such as Sodium sulfate anhydrous.min(99).
Enforcement of the present invention can make distributed more widely general, reserves enrich, contain the many glauberite resources of mud impurity is developed.
Best way of the invention process is to carry out in the saltcake mining area.Found the factory away from the mining area, high raw material transportation cost (general 4-5 ton raw material can be produced 1 ton of sodium sulfate product) will make exploitation lose economic implications, and the discharging of tailings also may cause environmental problem.
Claims (3)
- A kind of desliming impurity removing technology of shale type glauberite also can be called: the heavy desliming impurity removing technology that combines clearly of shale type saltcake ore deposit multistage sound attitude.Dissimilar solid saltcake ore deposit, so the saltcake work in-process of mud impurity contained, and the general thought of its purification all is the same, and is instant from → mud impurity removal → pure nitre liquid.The present invention combines some conventional technology (comprising equipment) as required according to sedimentation theory, forms a kind of new industrial flow of shale type saltcake ore deposit (comprising the saltcake work in-process that the mud foreign matter content is high) desliming removal of impurities.Feature of the present invention is:1. under stirring action, with the natural or underground ore bed hydromining liquid of artificial of heating, perhaps also have tailings embathe liquid etc. go molten from shale type saltcake ore deposit, thereby make the method for high density ore pulp.
- 2. be incubated and adding under the condition of flocculation agent, cleaner, enter the ore pulp of heavy clear equipment combination continuously, or fast or slow flow or leave standstill in turn in, mud impurity precipitates in the gravity settling mode and is removed continuously or intermittently, thereby makes the heavy desliming impurity removal process flow process that combines clearly of multistage, sound attitude of pure metabisulfite solution.
- 3. heavy clear equipment combination as claimed in claim 2 is divided into thick heavy equipment, dynamically heavy clear equipment and static heavy clear equipment.Dynamically heavy clear equipment can be merged into a heavy clear section with thick heavy equipment, also can merge into another heavy clear section with the heavy clear equipment of static state.
