Description
док отфильтровывают и вес фильтро вальной лепешки (включа маточный раствор) составл ет 120 г на 1 кг нейтрализованной суспензии. Состав фильтровальной лепешки, вес.%: , Са 6,k, Р 12, N 7,8; К 0,7; 50,7; F 0,2 и t, 1 the dock is filtered off and the weight of the filter cake (including the mother liquor) is 120 g per 1 kg of neutralized suspension. The composition of the filter cake, wt.%:, CA 6, k, R 12, N 7,8; K 0.7; 50.7; F 0,2 and t, 1
В фильтровальной лепешке содержитс 95% содержани цери в сыром фосфате и 50% иттри . Содержание земель в фильтровальной лепёшке 4,1% по весу, счита на , что соответствует 85% общего содерзканий редких земель в Кольском фосфа те.The filter cake contains 95% cerium in crude phosphate and 50% yttrium. The land content in the filter cake is 4.1% by weight, which is equivalent to 85% of the total rare earth content in the Kola phosphate.
Фильтруемость осадка соответствует примерно 3 суспензии на 1 м погруженной поверхности фильтра apautcuixaerocH барабанного фильтра при разрежении 100 Мм рт.ст. И тдлщине фильтровальной лепешки 5-6 мм.The filterability of the sediment corresponds to approximately 3 suspensions per 1 m of the immersed surface of the filter apautcuixaerocH drum filter with a vacuum of 100 Mm Hg. And tdline filter cake 5-6 mm.
Пример 2. В этом опыте примен ют тот же раствор, такое же добавление сульфата и метод снижени содержани фторидов, как в примере 1 Однако нейтрализацию газообразйьЫ аммиаком провод т при рН 2,5 (измеренном при разбавлении водой 1:10)Example 2. In this experiment, the same solution was used, the same sulfate addition and fluoride content reduction method as in Example 1 were used. However, the neutralization of gaseous ammonia was carried out at pH 2.5 (measured by diluting with water 1:10)
Врем пребывани в реакторе такое же, как в примере 1 и осадок немедленно отфильтровывают. Вес фильтровальной лепешки (включа маточный раствор) составл ет 120 г на 1 кг нейтрализованной суспензии. Состав фильтровальной лепешки, вес.%: Са 5,5; Р 10,8; Н 9,1; К 0,8; ЗОдб.О F 0,2 и k,k.The residence time in the reactor is the same as in Example 1 and the precipitate is immediately filtered off. The weight of the filter cake (including the mother liquor) is 120 g per 1 kg of neutralized suspension. The composition of the filter cake, wt.%: Ca 5.5; R 10.8; H 9.1; K 0.8; SODB O F 0,2 and k, k.
В фильтровальной лепешке присутствует почти 100% цери , содержащегос в сыром фосфате и 75% содержаще ,гос в ней иттри . В фильтровальной лепешке присутствует 93% содержани редких земель сырого фосфата. Фильтpyei CTb соответствует примерно 2 м УЧ суспензии на 1м погруженной фильтрующей поверхности барабанного вакуум-фильтра при разрежении 100 мм рт.ст. и толщине фильтровальной лепешки 5-6 мм.In the filter cake there is almost 100% cerium contained in the crude phosphate and 75% contained, it contains yttrium. The filter cake contains 93% of the rare earth content of raw phosphate. Filtpyei CTb corresponds to about 2 m of UCH suspension per 1 m of submerged filtering surface of the drum vacuum filter at a vacuum of 100 mm Hg. and the thickness of the filter cake 5-6 mm.
Предлагаемый способ позвол ет извлечь редкоземе;льные элементы из апатита на 85-93%.The proposed method allows rare-earth extraction; 85–93% of apatite is a common element.
