Magnetic separation process

PTMS magnetic separation

what is magnetic separation in science?

Quartz sand pickling magnetic separation

     Acid washed quartz sand is wet acid pickling. It uses various acids. Such as hydrochloric acid, sulfuric acid, oxalic acid, hydrofluoric acid and so on. technical parameter

Working principle:

     Crushing before pickling is done by wet crushing. Some of them are broken by mechanical means, such as hammering and breaking. The broken materials contain a lot of mechanical iron. Mechanical iron and quartz sand react slowly in water. Usually after a few days, mechanical iron will oxidize into trivalent iron and turn red and yellow. If the acid is soaked, the oxidation of iron in the exposed air is faster.

     Quartz sand crushing - washing - magnetic separation - acid leaching - water washing - dehydration - drying

     When quartz sand is washed and washed, some impurities can be removed. Magnetic separation can remove more than 99% of the mechanical iron. Acid leaching can be added to a variety of acid in accordance with the actual conditions. Acid leaching equipment must be resistant to acid and alkali plastic containers. Stainless steel is not recommended. Some acid corroded stainless steel. For acid leaching, it is recommended to use reactors or containers with heating and stirring. The acid is soaked more thoroughly and the reaction is more full. The wash also needs to be stirred, and the cleaning is complete.

What is the difference between the pickled quartz sand and the ordinary quartz sand

1. The purity of the quartz sand is higher than the silica fine of the ordinary quartz sand, the acid washing quartz sand, and the fine quartz sand, SiO2 99.7%, and the SiO2 of the ordinary quartz sand 94%.
2. The acid washing quartz sand needs to go through impurities, magnetic separation, flotation, acid leaching, purification and other complex processes can be obtained pure quartz sand and gravel, and ordinary quartz sand will not be miscellaneous. That is to say, the more times it purify, the higher the purity of its gravel.
3. The color is different, the color of acid washing quartz sand is pure white or colorless and transparent color. It can be used in glass, ceramic, steel casting, rubber, paint, paint, pure water treatment and so on. The ordinary quartz sand is pale yellow, the appearance will have light yellow sugar coating, generally used in sewage treatment, artificial floor and so on.

4. The use of life, acid washing quartz sand generally can be used three to five years of time to be assured of use; and ordinary quartz sand can be replaced once a year to two years, or the water quality treatment effect is not as good as in the past.

5. The main purpose and benefits of pickling quartz sand filter material: pickling is the carrier of the carrier 6mol/L hydrochloric acid soak 2H or concentrated hydrochloric acid to boil 30min, filter, wash with water to neutral, drying. Acid washing removes iron and aluminum on the surface; in general, it removes impurities. No matter whether it is used for water treatment filtration or others, there is no impurity in use.The technological process of washing quartz sand filter material is as follows:
1.We should first select quartz minerals with good selection, which is manually selected, and generally recruit some surplus rural labor force to choose.
2.Then the quality of quartz ore determines the concentration of hydrochloric acid and soaking time during acid pickling.
3.Next is broken, and now the quartz sand production equipment is integrated. After the ore enters the equipment, it is finished. But pickling quartz sand is not suitable for this equipment, because ore can not directly enter the shale shaker after crushing, but to enter the acid pond, so it is not suitable for integrated equipment.
4.The concentration of hydrochloric acid is generally about 30%, and soaking time is about 24 hours. The soaked quartz sand has no impurities, and the color becomes glittering and translucent, then it is sieved and flushed, and the sieves and flushing are completed in one set of equipment. The quartz sand produced in this way is good for reverse osmosis and desalting equipment.
