what is magnetic separation method in hindi？

The most important process for processing quartz sand into high-purity quartz sand is purification. There are two steps: initial purification and fine purification.
     First, the initial purification:
  1 Scrubbing is the removal of the film iron, the bonding and muddy impurities on the surface of the quartz sand by mechanical force and the abrasive stripping force of the sand and further shredding the unassembled mineral aggregate. There are mainly mechanical scrubbing and ultrasonic scrubbing.
2 Magnetic separation: Hematite, limonite and biotite, including continuous body particles, can be removed to the utmost extent. There are mainly wet magnetic magnetic separators or high gradient magnetic separators. 3 Flotation: With the increasing awareness of environmental protection, the fluorine-free flotation method is now used. 4 Magnetic carrier sorting: In the mixed suspension, the magnet particles are selectively attached to a mineral surface, and then the magnetic particles are used to remove the mineral particles covered by the magnetite.
    Second, the refined purification process:
Generally, after initial purification, the SIO2 content in quartz sand can reach 99.3%-99.9%. To obtain higher purity, it needs to be refined.
1 Microbial leaching: The thin film iron or dip-dyed iron on the surface of quartz sand particles is leached with microorganisms. The removal rate of Fe2O3, a recently developed iron removal technology, is above 75%.
2 Acid leaching: Acid leaching is the fruitful process of preparing high-purity quartz sand. It has the effect and effect of washing, flotation, magnetic separation and other methods, which can effectively remove the surface of quartz sand particles or mosaic in the form of inclusions. Impurities in the particles are important high purity quartz processing tools. Acidity, time, temperature, acid washing, process equipment, etc. are the main factors affecting the pickling effect.
Third, China's high-purity quartz sand processing technology features: 1 high purity of reagents 2 strong reagent corrosion 3 material standards strict 4 environmental requirements 5 high safety requirements
