Pure silica sand processing techniques is a purification technology, which is mainly to remove small or trace impurities in the silica sand to obtain refined silica sand or high purity silica sand. The purification processes of silica sand at home and abroad mainly include grading, desliming, scrubbing, magnetic separation, flotation, acid pickling, etc.

Features
1. Advanced pickling technology and short reaction time;
2. Closed pickling equipment, pollution-free production process;
3.The ultra-white and ultra-pure silica sand products can be obtained;
4. The production line has low energy consumption and no power consumption.
5. The production line operates at room temperature with strong adaptability
The technical process
The prepared silica sand enters the pickling equipment through feeding devices. In the pickling equipment, the silica sand and acid solution are fully mixed. The reaction time is set according to the properties of silica sand, and the impurities are discharged together with the pickling liquid. After reagent removal and dewatering, the final high purity silica sand will be obtained.
