According to the mineral dressing method, raw limonite ores are subjected to particle gradation by using the grading screen, and then required ores and unwanted impurities are separated through a wind force specific gravity mineral dressing mechanism, thereby obtaining the limonite ores of an ideal grade. Thus, the mineral dressing machine and the mineral dressing method have the advantages that the investment cost on equipment is low, the process is simple, the power consumption is little, the levigation, calcinations and addition of medicaments are not required, and an effective mineral dressing effect can be achieved while the production technological process is simplified and the production cost is reduced.
Description
Technical field
The present invention relates to pneumatic separation field, refer to especially a kind of limonite ore wind-force specific gravity concentrator and the method that adopts this ore separators to carry out ore dressing.
Background technology
World's limonite resource reserve is larger, and it is not a kind of mineral, is mainly goethite, liquid drugs injection iron ore, is weak magnetic mineral, and firmness change is large, argillization very easily in broken grinding process.Owing to being subject to the restriction of the natural property of limonite, adopt physical upgrading method iron concentrate grade to be difficult to reach 60%, and be difficult to obtain higher metal recovery rate, belong to one of iron ore of complicated difficult choosing.Therefore, limonite because grade is low, scaling loss compared with large, affect the welcome that the capacity factor of a blast furnace is not smelted always, the value of its exploitation is also subject to great restriction.But because scaling loss is compared with increasing substantially greatly iron concentrate grade, and because being easy to smelting compared with loose, be also important iron ore deposit after limonite roasting.
Along with iron ore deposit high-quality and easy choosing reduces gradually, especially the fast development of China's steel and iron industry has highlighted iron ore deposit and has put upon the full stretch, therefore the efficient technique of preparing of limonite becomes the main direction of research gradually, and has obtained in recent years obvious progress.
As a kind of iron-smelting raw material, at present, limonite ore beneficiation method is divided into following three kinds of methods substantially:
1. fragmentation, ball milling, washing, then use gravity to carry out ore dressing.
2. fragmentation, ball milling, the flotation again of interpolation medicament.
3. fragmentation, balling-up, sintering, ball milling, then magnetic separation etc.
So because the special constituent of limonite is difficult to carry out sorting, the equipment investment of above-mentioned beneficiation method is large, technique is numerous and diverse, beneficiation cost is high, and low-grade limonite ore is difficult to carry out ore dressing.
Summary of the invention
In view of this, the object of the invention is to propose a kind of ore separators and beneficiation method, solve an ore dressing difficult problem for low-grade impure limonite ore.
Based on above-mentioned purpose a kind of ore separators provided by the invention, comprise classifying drum screen and sorting mechanism, described sorting mechanism comprises sorting mechanism charging aperture, air channel, air inlet, concentrate outlet, tailings discharge gate and wind-force adjuster, and the quantity of described sorting mechanism is identical with the progression of classifying drum screen;
Wherein, described sorting mechanism is positioned at the below of classifying drum screen, and the raw ore discharging opening of classifying drum screen is connected with sorting mechanism charging aperture, makes the raw ore particle of classified rotary screen classification enter respectively corresponding sorting mechanism; Described sorting mechanism charging aperture is positioned at the top in described air channel, and the one end in described air channel is provided with air inlet, and the other end is provided with tailings discharge gate; Described wind-force adjuster is positioned at air inlet one side, for regulating the wind-force in air channel; The bottom in described air channel is provided with concentrate outlet between air inlet and tailings discharge gate, after described sorting mechanism charging aperture is positioned at air inlet, before concentrate outlet.
Preferably, the downward-sloping setting in air channel between described concentrate outlet and tailings discharge gate.
Alternatively, between described concentrate outlet and tailings discharge gate, be also provided with the outlet of secondary concentrate.
Alternatively, one side the edge of described secondary concentrate outlet near the baffle plate that is provided with of tailings discharge gate.
Preferably, between the outlet of described air inlet and concentrate, be also provided with wind direction hyoplastron, and before described wind direction hyoplastron is positioned at sorting mechanism charging aperture, for regulating the wind-force direction in air channel.
Preferably, described classifying drum screen is obliquely installed, and its raw ore discharging opening is lower than raw ore charging aperture, and described classifying drum screen is three grades of rotary screens, and the quantity of described sorting mechanism is 3.
A beneficiation method of using ore separators provided by the invention, comprises the following steps:
A. limonite ore tcrude ore is carried out to fragmentation, then sent into the charging aperture of classifying drum screen;
B. the tcrude ore particle being broken is at classifying drum screen internal classification;
C. the tcrude ore through sorting cylinder sieve classification enters respectively corresponding sorting mechanism charging aperture, arrives air channel, at air inlet place, adds blast in to air channel, under, direction big or small at the wind-force of debug, carries out gravity separation; Impurity particle compared with lightweight is discharged fast by wind-force in air channel, and the limonite ore particle of heavier quality can not be discharged under the effect of wind-force, but be deposited in bottom, air channel, by wind-force, be slowly pushed to concentrate outlet discharge, remaining impurity particle is discharged by tailings discharge gate by wind-force.
Preferably, described in the maximum gauge≤10mm of the tcrude ore particle that is broken, and under classifying drum screen effect, be divided into carse, medium and small three ranks.
Alternatively, when described ore particles carries out sorting in air channel, by wind-force adjuster and/or the wind direction hyoplastron at air inlet place, wind-force size and wind-force direction in air channel are regulated, with this, decide the height of concentrate grade.
Preferably, it is characterized in that, described in the impurity particle that is discharged from before discharging, also have a small amount of limonite ore particle, by the outlet of secondary concentrate, discharge this ore particles, remaining impurity particle is discharged by tailings discharge gate by wind-force.
As can be seen from above, ore separators provided by the invention and beneficiation method, solved the ore dressing difficult problem of low-grade impure limonite ore.The present invention first by classifying screen by the tcrude ore gradation of limonite ore, then by wind-force specific gravity concentrator structure, required ore and unwanted impurity are separated, reach the limonite ore of desirable grade.Therefore, present device cost of investment is low, technique is simple, power consumption is little, it is levigate not need, calcine, add medicament, when having simplified production procedure, having reduced production cost, can reach again effective ore dressing effect.
