We all know that, Refined quartz sand In the production process, it is a very critical whole process to promote iron removal, which is mainly to develop Quartz sand Of. How to remove iron when producing refined quartz sand?
Generally speaking, there are three methods of iron removal: mechanical equipment scrubbing, magnetic separation equipment and ultrasonic wave. The iron removal by mechanical equipment scrubbing is mainly to remove the iron residue outside the raw quartz ore through the actual effect of external force. Mechanical equipment scrubbing also includes rod scrubbing and mechanical equipment scrubbing. When mechanical equipment is used for iron removal, some aqueous solutions are required to cooperate with each other, and the concentration of coal slurry is set to a certain ratio to conduct iron removal and carding of raw ore quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with small output, and the quality of raw quartz sand may be very good.
The magnetic separation equipment removes iron through the chemical properties of iron. The magnetic separation equipment has two methods, dry separation and wet separation, each of which has its own advantages. In application, the composition of raw ore quartz sand should be measured first as far as possible. If the raw ore quartz sand contains weak magnetic residues such as hematite, limonite and biotite with intergrowth particles in it, only wet separation can be used, However, the disadvantages of wet separation are large power consumption, simple material damage, large water demand for production, and high work and maintenance costs. If the above residues are not available, dry separation can be used. Compared with wet separation, it has very low cost and maintenance.
It refers to ultrasonic iron removal. This method is mainly used to remove the secondary cast iron plastic film on the surface of quartz sand particles. The cleaning method of mechanical equipment is not good. Each of the three methods has its own advantages and characteristics, which should be selected according to the actual situation.
