Production of fluoridated salt.
Sodium and potassium fluoride are used for the fluoridation of household salt. Addition of fluoride is carried out either by the wet or the dry process. Qualitatively good fluoridated salt can be produced by using either method. In the wet process, a solution of potassium fluoride is mixed homogeneously with the salt. For the dry mixture, only sodium fluoride with a small granule size is suitable. Apart from the mixing methods used by the larger salt manufacturers, there are low-cost solutions for very small producers.
