They are both unsmooth and beautiful. In fact, Quartz sand The same is true for industrial raw materials, but such delicacies are not detailed. If you want to have Refined quartz sand You must promote iron removal in the production link, which is a very critical whole process, and the key goal is to purify quartz sand. So, how to remove iron in the production of refined quartz sand?

Mechanical scrubbing and iron removal method: mechanical scrubbing and iron removal is mainly to remove iron residue except quartz sand ore according to external force.

There are two kinds of mechanical scrubbing: lifting scrubbing and mechanical scrubbing. When mechanical iron removal is applied, some aqueous solutions shall be used to cooperate with each other, and the concentration of coal slurry exceeds the proportion to remove iron from magnesite quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with low production and use value or when the quality of magnesite quartz sand is good.

Iron removal by magnetic separation: iron removal by magnetic separation is based on the physical characteristics of iron.

There are two ways of magnetic separation: dry separation and wet separation. Each way has its own advantages. In use, White sandstone The composition of raw quartz sand shall be determined as far as possible. If the original quartz sand belt contains hematite, limonite, biotite and other weak magnetic residues. It contains intergrowth particles, which can only be separated by dry method. However, the disadvantages of wet separation are high energy consumption, simple material damage, large water consumption, and relatively high maintenance costs in work. If there is no residue above, dry separation can be used. Compared with dry separation, the cost and maintenance costs are very low.

Ultrasonic iron removal method: This method is mainly used to remove the secondary cast iron film on the surface of quartz sand particles. Mechanical scrubbing is not suitable. Each of the three methods has its own advantages and characteristics, which should be selected according to the actual situation.
