Abstract
Improvements introduced in the procedures for obtaining calcium fluoride from fluosilºcico acid, starting from the reaction between fluosilicic acid and a calcium salt or base, preferably calcium carbonate, to give calcium fluoride, silica, carbon dioxide and water, in a suspension that is filtered or decanted leaving a pulp containing mainly calcium fluoride and silica, essentially characterized in that to the alluded pulp water is added in sufficient quantity so that there remains a suspension with a lower solid content preferably 25%, stirring during a some time, and then filtered or discarded, separating a solution that extracts much of the silica in colloidal state, while in the final pulp or residue once dry, has a richness in calcium fluoride not less than 80%, being the silica content less than 6%.
