Description
Technical field
The present invention relates to the method for purification of quartz sand, especially relate to a kind of efficient magnetic selection method of quartz sand.
Background technology
Quartz sand is irreplaceable basic material in national strategy property and the pillar industry development, is widely used in high-tech sectors such as glass, photovoltaic, photoelectricity and space flight.Along with developing rapidly of these fields, the demand of quartz sand is increased day by day, and good quartz mine resource is day by day exhausted along with the continuous exploitation in age.How common quartz sand resources is fully utilized through purification, just seem most important.
The tradition method of purification mainly is to realize through methods such as flotation, acidleach, traditional magnetic separation.Acidleach and flotation all will be added chemical substance in process; These chemical substances not only exist the hidden danger of environmental protection aspect; And in the quartz sand product of producing because of residual the acid or alkaline medicament that is added, can cause influence in various degree to follow-up technology and equipment, and production process receives the influence of many factors such as temperature, concentration, pH value; Production operation is poor, and not looked at by the parent of enterprise.
The tradition method of purification also adopts the various strong bar magnet of quantity (surface electric field intensity is about 0.8 tesla) to be placed in the irrigation canals and ditches manual work mostly and cleans successively; Reach the purpose of deironing; So not only workman's workload is big, and receives numerous human factors such as cleaning frequency to influence bad control in the production.Drum magnetic separator because of magnetic force little and material can not with reasons such as drum surface fully contacts, de-ferrous effect is not good yet when producing this quartz-like sand.And no matter be strong bar magnet or drum magnetic separator along with the growth of service time, all can decay to some extent in magnetic field.
In addition, traditional method of purification is because of technology imperfection and equipment backwardness, and not only production is difficult to the formation scale, and aspect purification, also is difficult to obtain positive effect.
Summary of the invention
The object of the invention just provide a kind of purity that increases substantially quartz sand, zero-emission, no waste produce, pollution-free, production capacity is high, specific energy consumption is low, be suitable for the efficient magnetic selection method of large-scale production.
The objective of the invention is to realize like this:
A kind of efficient magnetic selection method of quartz sand, characteristic is:
1, fragmentation-washup: quartz mine is slightly broken to the bulk of 5cm * 5cm through jaw crusher; Get into the carefully broken fine ore to 1cm * 1cm of gyratory crusher; With belt fine ore is delivered on the vibratory sieve; And utilize water under high pressure that the fine ore on the vibratory sieve is washed, and remove the impurity components such as clay on fine ore surface, sieve material down obtains can be used as first byproduct of simple glass raw material through the desliming of a desliming bucket, after concentrated: quartzy general sand; The overflow of a desliming bucket gets into thickening pond;
2, ore grinding-first classification: the fine ore that will wash is sent into rod mill earlier and is carried out wet milling, the ore pulp of wearing into, and getting into screen cloth is that 20 purpose cylinder roller screens carry out first classification, the material on the sieve is delivered to rod mill with belt and regrinds;
3, desliming: the ore pulp under the cylinder rotary screen gets into No. two desliming buckets, screens out mud and mica group light weight sundries in the ore pulp, and the overflow of No. two desliming buckets gets into thickening pond;
4, magnetic separation: the underflow breeze of desliming bucket is successively through cartridge type low intensity magnetic separation machine and upright ring pulsating high gradient intensity magnetic separator; The field intensity of cartridge type low intensity magnetic separation machine is 0.1～0.5 tesla; Main the background field intensity of upright ring pulsating high gradient intensity magnetic separator requires to reach 1 tesla with the mechanical iron that gets in the strongly magnetic mineral and the process that remove in the quartz sand, and medium adopts 1.5 mm rod medium; Feed ore concentration is controlled at 10～15%, with removing biotite, the Fe in the quartz sand
