Abstract
The paper presents the research results on integrative processing of datolite ore using the fluorite concentrate and ammonium sulphate. It is shown that fluorination can be carried out without expensive ammonium bifluoride, using chemical interactions fluorite concentrate and ammonium sulphate. The products are easily separated to obtain complex fluorammonium salts of boron, silicon and calcium sulphate in the gypsum form.
