Recycling fluorosilicic acid to produce sodium fluoride
We have studied the processing of fluorosilicic acid through its interaction with sodium hydroxide with sodium fluoride producing and sodium silicate solution. The optimal technological process conditions are determined for the quality product sodium fluoride obtaining. In order to reduce the loss of the desired product, conducted experiments, the choice of solution for washing the precipitate. The parameters of the washing process of sodium fluoride, in which the release of the particles of the desired product with washing solution is minimal are selected.
