Which is better wet or dry beneficiation of silica sand?

Purity of silica sand up to 99,9% with no water consumption, how is it possible?

In the regions of Central Asia, the Middle East and Africa, there is a challenge with the profitability of wet separation, which is usually considered more efficient than dry separation.

What do you think about it?

We are confident that dry separation can be more effective and we have developed solutions that prove that. The solution is based on the use of high inductive ERGA RollMag which allows fulfill tasks with a capacity of more than 10 tons per hour and purification of sands up to 99.9% reducing Fe2O3 content to 200-100 ppm.
