Abstract

Раскрыты способы получения раствора ионов кальция из извести (например карбидной извести). В одном аспекте способ содержит: (i) обработку извести водным раствором полигидроксисоединения (предпочтительно сорбита), имеющего три или более гидроксигрупп и прямую цепь из 3-8 атомов углерода, и (ii) необязательно отделение нерастворимых примесей от раствора, полученного после (i). В другом аспекте способ содержит: (iii) обработку карбидной извести водным раствором полигидроксисоединения (например сорбита или сахарозы) для извлечения кальция из карбидной извести и (iv) отделение нерастворимых примесей от раствора, полученного от (i). Полученные растворы могут быть обработаны осаждающим агентом для получения твердого, содержащего кальций продукта. Продуктом может быть карбонат кальция, полученный обработкой раствора диоксидом углерода в качестве осаждающего агента.Международная заявка была опубликована вместе с отчетом о международном поиске.
