The strontium ore beneficiation method adopts a full flotation process, so that the resource recovery rate of the strontium ore is improved, the recovery rate of strontium sulphate is improved from about 70% in the prior art to above 93%, and the concentrate grade is kept at 72%.
Description
Technical field
The present invention relates to the technique of preparing field, particularly a kind of strontium ore deposit technique of preparing.
Background technology
Ore dressing claims again " mineral processing ", exactly the useful constituent in the ore is extracted by certain method.With physics or chemical method with the valuable mineral in the raw mineral materials and useless mineral (usually claiming gangue) or toxic mineral separately, or the technical process that multiple valuable mineral is separated.
Strontium ore deposit technique of preparing mainly contains the modes such as gravity separation, flotation.
Gravity separation be utilize be sorted the difference of relative density between mineral grain, granularity, shape and in medium (water, air or the larger liquid of other relative densities) movement rate and direction different, make it beneficiation method separated from one another.Gravity separation process middling particle will be subject to mechanical force that gravity (if in centrifugal force field then mainly be centrifugal force), equipment applies and the active force of medium, the ingenious combination of these power just makes the different ore particle of density produce different movement velocity and movement locus, finally can make them separated from one another.Gravity separation is widely used in processing coal, non-ferrous metal, rare metal, precious metal ore, also is used for the processing to non-metallic ores such as asbestos, diamonds.Floatation is once called as floating separation, is to use more a kind of beneficiating method in the mineral processing production, is to utilize the difference of mineral surfaces physicochemical properties to select a kind of method of minute ore.
Gravity separation is suitable for the higher ore deposit of the grade of ore, and content of strontium is higher in the mine tailing, and the bit comparison of Commercial Ore product is low, and the rate of recovery of strontium is lower.
Summary of the invention
The present invention proposes the beneficiation method in a kind of low-grade strontium ore deposit, reduces the environmental protection treatment expense, has improved the grade of Commercial Ore, and has improved the energy-saving and emission-reduction level that strontium is produced.
A kind of strontium of the present invention ore deposit beneficiation method may further comprise the steps:
1) obtains milling ore from crude ore bin.
2) milling ore is carried out fragmentation.
3) breaking ores is carried out ball milling.
4) the ball milling ore that obtains of ball milling carries out classification, and classification obtains satisfactory breeze and coarse fodder.The coarse fodder that classification is obtained carries out ball milling together with water again.
5) the satisfactory breeze of classification is put into agitator, in agitator, add medicament and stir.
6) the stirring material that stirring is obtained carries out flotation and selects sulphur.
7) flotation is selected the breeze that obtains behind the sulphur carry out the strontium flotation.
8) flotation is selected in the strontium step remaining ore deposit, selected strontium ore deposit then to carry out mine tailing to process.
Milling ore can be the lower ore of head grade.
Fragmentation to milling ore comprises coarse crushing, again the coarse crushing ore that obtains is put into reciprocating sieve.The ore that obtains by reciprocating sieve vibrations carries out in small, broken bits again, and the ore in small, broken bits that obtains in small, broken bits is still put into reciprocating sieve, obtains breaking ores.
Flotation is selected sulphur to comprise and is selected sulphur, concentrator is put in the sulphur ore deposit of selecting, and passes through filtering means dehydration again, obtains at last the sulphur concentrate.
The strontium flotation comprises that fast choosing selects strontium, then concentrator is put in the ore deposit of selecting, and passes through filtering means dehydration again, obtain the strontium concentrate, it is selected that a part of selecting strontium to obtain soon selects the strontium ore deposit to carry out soon, and concentrator is still put in the selected selected strontium ore deposit that obtains, refilter dehydration, obtain the strontium concentrate.
The mine tailing processing comprises puts into concentrator to remaining ore deposit, passes through filtering means dehydration again, obtains mine tailing.
The invention provides a kind of strontium ore deposit beneficiation method, milling ore through behind the crushing raw ore, is entered the grind grading stage, satisfactory breeze adds flotation agent, enters flotation device and carries out ore dressing.At first carry out the sulphur flotation, reclaim pyrite, then carry out the strontium flotation, high-grade pyrite and strontium ore deposit through the thickening filtration dehydration, namely can be used as Commercial Ore respectively.
The buoyancy ore dressing can be processed the lower ore deposit of head grade, and the product bit comparison of Commercial Ore is high, and the rate of recovery of strontium is also higher, the Sulfur iron ore of association in the ore can be separated simultaneously, reduces the discharging of sulfur dioxide in the strontium carbonate production.
Process using bulk flotation technological process of the present invention improves the strontium ore resource rate of recovery, and the strontium sulfate rate of recovery rises to more than 93% by original about 70%, and concentrate grade remains on 72%.
