Description
(54) СПОСОБ ПОЛУЧЕНИЯ СУЛЬФАТОВ ЩЕЛОЧНЫХ МЕТАЛЛОВ И АЛЮМОСИЛИКАТОВ КАЛЬЦИЯ(54) METHOD FOR OBTAINING SULPHATE ALKALINE METALS AND CALCIUM ALUMOSILICATES
одна иа которых содержит 39%K5 SO4 и 57% Na,jSO , друга - алюмосиликат кальци . Потери сульфата кали и сульфата натри составл ют, соответственно, 0,5 и 2,0%, пылеунос не превышает 0,2%.one of which contains 39% K5 SO4 and 57% Na, jSO, the other is calcium aluminum silicate. The losses of potassium sulfate and sodium sulfate are 0.5 and 2.0%, respectively, and the dust content does not exceed 0.2%.
П р и м е р 2. Нефелинфосфогипсовую шихту, состо щую из 1 части нефелина и 0,3 частей фосфогипса брикетирую под да лением 50 кг/см и подают в обжиговую печь, состо щую из зон сушки, прокалки и охлаждени . Температура сушки- 500 С, температура обжига - 1100 С, врем об жига-4 час. Плав охлаждают до 150 С, раздел ют, выщелачивают сульфат кали водой и кристаллизуют его из раствора.EXAMPLE 2. A nepheline phosphogyptic mixture consisting of 1 part nepheline and 0.3 parts of phosphogypsum is briquetted at a rate of 50 kg / cm and fed into a kiln consisting of drying, calcining and cooling zones. The drying temperature is 500 ° C, the firing temperature is 1100 ° C, and the firing time is 4 hours. The melt is cooled to 150 ° C, separated, the potassium sulfate is leached with water and crystallized from solution.
На 1т нефелина получают 130 кг суль-фата кали , потери сульфата кали - 0,5%At 1 ton of nepheline, 130 kg of potassium sulfate are obtained; potassium sulfate loss is 0.5%
пылеунос - 0,2%.pyleunos - 0.2%.
