Claims (2)

1. Способ обескремнивания природных минералов и руд, включающий их дробление, размол и химическое обогащение, отличающийся тем, что размолотый продукт смешивают с фторид-бифторидом аммония в массовом отношении: (SiO2 в сырье: фторид-бифторид аммония)=1:1,5-1:5,5 и прокаливают при 100-500°С с температурным градиентом 5-10°С / мин.1. The method of desiliconization of natural minerals and ores, including their crushing, grinding and chemical enrichment, characterized in that the ground product is mixed with ammonium fluoride bifluoride in a mass ratio: (SiO 2 in the feed: ammonium fluoride bifluoride) = 1: 1, 5-1: 5.5 and calcined at 100-500 ° C with a temperature gradient of 5-10 ° C / min. 2. Способ по п.1, отличающийся тем, что выделяющуюся при термообработке газовую фазу охлаждают, отделяют десублимат и используют его в качестве фторсырья для получения фторсоединений и фторид-бифторида аммония, возвращаемого в “голову” процесса.2. The method according to claim 1, characterized in that the gas phase released during the heat treatment is cooled, desublimate is separated and used as a fluorine source to produce fluorine compounds and ammonium fluoride bifluoride returned to the process head.
