Description

чении конверси  проходит неполно и степень очистки снижаетс .The conversion is incomplete and the degree of purification decreases.

К 25 г сухого стронцийсодержащего сульфатного осадка, вьщеленного из аппатита, добавл ют 3 г карбоната аммони ,.60 мл воды и вьвдерживают в Te4iHHe ч при 45 С при перемешивании, после чего осадок отдел ют и обрабатывают 80 мл азотной кислоты с концентрацией 150 г/л. Осадок и фильтрат анализируют. Результаты анализа приведены в таблице.3 g of ammonium carbonate, .60 ml of water are added to 25 g of dry strontium-containing sulphate precipitate isolated from appatite, .60 ml of water and kept in Te4iHHe h at 45 ° C with stirring. l The precipitate and the filtrate are analyzed. The results of the analysis are shown in the table.
