Abstract
A process for separating flaky ore from granular ore includes granularity classifying with screening net, shape separation by hydraulic stage, and proportional mixing the deposited ores. Said hydraulic shape separation can use fine-particle hydraulic cyclone separator, or use sedimentation tank for coarse particles and hydraulic cyclone separator for fine particles. Its advantages are high efficiency and accurate separation.
Description
The invention belongs to a kind of sheet and fibrous mineral and select point-score.
This sheet and fibrous mineral select point-score, are used for ore dressing, building materials industry is selected branch to sheet and fibrous mineral, material.
The hydrocyclone that uses only is used for the mineral desliming and carries out classification by thin mineral granularity at present.Spiral classifier system carries out classification to the following fine granules desliming of 2mm with by granularity.Dense media choosing divides and is applicable to that different minerals particle proportion differs 0.3T/m3 when above, and expense is higher.Friction then is that mineral are divided into narrow grade with the spring ore dressing, spreads out on friction plate or counterflow screen and utilizes frictional force difference to select branch, and efficient is lower.Only be suitable for than coarse fraction, than long fibre.And chemical flotation rule is to use different chemical agent flotation at different minerals, and has the problem that is separated into pint chemical agent.
The objective of the invention is to overcome the deficiency of above method, remedy the formed blank of above method, in each grade, all there is difference of specific gravity＜0.3T/m3 such as each mineral in the granite, but there is shape difference-sheet and granular, at sheet and the process that a kind of efficient sorting is provided separating of fibrous mineral.
Purpose of the present invention can reach by the following technical programs: at first with former mineral with the narrow grades of 3-6 level of sieving at different levels, all select sheet thereafter, or coarse fraction is selected sheet with flow tank, fine fraction with hydrocyclone with hydrocyclone.Whether be made into sheet, the pelletized product that meets certain grading curve by the product requirement decision at last by the grade grating.The essence of the technical program is earlier by the screen size classification, after utilize in the same narrow grade difform particle sink-float difference in moving water to select sheet.Process implementing example shown in the accompanying drawing 1,2 for example.The present invention compares with above-mentioned prior art, has the following advantages:
1, be applicable to difference in specific gravity less than 0.3T/m3, but shape difference is indicated as sheet and granular ore particle material grain sorting.
2, be applicable to economically, technically should not use dense media rub broken soft particle method and the ore dressing of jigging method.Use current choosing efficiently to divide.
3, the present invention is a physical method, does not have any chemical agent and adds, and has avoided the chemical contamination of sewage and the chemical agent that takes off of finished product to handle.
4, the hydrocyclone row mouth that uses among the present invention is than little, and the sheet ore deposit accounts for the raw ore solid than in 15%.Mica has only 7-8% in for example general granite.
5, the at different levels granular finished product that forms among the present invention can be formed the continuous grading mineral aggregate that conforms with certain curve as required.After for example granite being removed mica, can form the concrete artificial sand of certain fineness modulus by a certain percentage.By the modulus of fineness difference of control sand, and then control concrete glue material total amount and quality.
The picture of accompanying drawing is described as follows: Fig. 1 is the schematic diagram of implementing process flow process example 1, wherein waterpower separating method hydrocyclone.
Fig. 2 is the schematic diagram of implementing process flow process example 2, and wherein coarse fraction uses flow tank, fine fraction to use hydrocyclone in the waterpower separating method.
Being described as follows of each label among the figure: the former mineral aggregate of 1-, 2-double deck screen, 3-single-deck screen, the 4-single-deck screen, the 5-sand pump, 6-hydrocyclone, 7-sheet finished product dewatering screen, 8-sheet finished product heap storehouse, the granular finished product dewatering screen of 9-, the granular finished product heap of 10-storehouse, 11-rod mill, 12-waterpower flow tank, 13-sewage treatment plant.
1 be described in detail embodiments of the invention 1 in conjunction with the accompanying drawings:
1, raw ore 1 is sent to rod mill 11 through double deck screen 2 blankings greater than the 5mm particle, the closed circuit double deck screen 2 that returns in mill back; Double deck screen 2 also will be divided into greater than 1.25mm with less than the 1.25mm two-stage less than the 5mm raw material simultaneously.
2, be divided into greater than 5～2.5mm, 1.25～2.5mm two-stage through single-deck screen 3 greater than 1.25mm level material;＜1.25mm level material through single-deck screen 4 be divided into 0.3～1.25mm,＜the 0.3mm two-stage.
3, the narrow grade material of level Four is sent into hydrocyclone 6 by sand pump 5 respectively.
4, be sent to dewatering screen 7 dehydrations after the overflow of first three grade of hydrocyclone mixes in proportion, obtain the sheet ore particle, be sent to sheet finished product heap storehouse 8.
5, send dewatering screen 9 dehydrations after hydrocyclone sand settings at different levels mix, obtain granular finished product and send granular warehouse for finished product 10, the overflow and the dirty sewage treatment plant 13 that all is sent to of dewatering screen sieve of fine fraction hydrocyclone.
Accompanying drawing 2 just greater than 2.5mm, be not with hydrocyclone sorting sheet and granular less than 2.5mm level material, but with waterpower flow tank 12 sorting sheets, granular ore particle.All the other are with accompanying drawing 1.
Claims (4)
1, a kind of sheet and fibrous mineral select point-score, it is characterized in that: at first by screen clothes at different levels ore particle is divided into the narrow grade material of 3-6 level; With the waterpower separating method sheet in the same narrow grade material is separated with shot-like particle again; At last finished product material at different levels are mixed in proportion.
2, sheet according to claim 1 and fibrous mineral select point-score, it is characterized in that: described waterpower separating method is the hydrocyclone with narrow grade.
3, sheet according to claim 1 and fibrous mineral select point-score, it is characterized in that: described waterpower separating method coarse fraction also can use flow tank, and fine fraction uses narrow grade hydrocyclone.
4, sheet according to claim 1 and fibrous mineral select point-score, it is characterized in that: described narrow grade material behind blanking sheet mineral mixes in proportion forms the mineral aggregate that conforms with certain grading curve.
