Description

105°С. Руды раствор ют в течение 40 мин в интервале температур 6580 С , охлаждают до температуры , отфильтровывеиот полученный шенит (KjSO Mg-SO ) . Иенит разлагают водой при температуре в соотношении Ж:Т 0,9.105 ° C. The ore is dissolved within 40 minutes in the temperature range 6580 ° C, cooled to a temperature filtered off from the resulting shenite (KjSO Mg-SO). Ienit decompose with water at a temperature in the ratio W: T 0.9.

Полученный сульфат кали  высушивают при температуре 100 и взвешивают. Выход продукта 55,2%.The resulting potassium sulfate is dried at a temperature of 100 and weighed. The product yield is 55.2%.

Пример 2. Берут 1000 кг кад1ннто-лангбейнитовой руды следующего состава: каинита - 18,64%, ланрбейнита - 15,84% и сильвина 2,74%, и добавл ют 220 кг сильви 1И-. товбй руды Соликамского месторождени , содержащей 30% КСв. Отношение сил винитовой руды к калийной полиминеральной руде составл ет 2:9,Example 2. 1000 kg of cad1nto-langbeinite ore of the following composition is taken: kainit - 18.64%, lanrbeinit - 15.84% and sylvite 2.74%, and 220 kg of sylvi 1I- are added. Tovby ore of the Solikamskoye deposit containing 30% KSv. The ratio of vinite ore to potash mineral mineral ore is 2: 9

Смесь руд загружают одновременно в растворитель, подава  в него раствор юйзий щелок температурой 100105 С , Руду раствор ют в течение 40 мин в интервале температур ЬЬВО С , охлаждают до температуры 20с, .отфильтровывают полученный шенит (К2.3О4Г Mg SO46H,jO), Шенит разлагаютThe mixture of ores is loaded simultaneously into the solvent, feeding it with a solution of lyuze lye with a temperature of 10,010 ° C, the ore is dissolved for 40 minutes in the temperature range LBBO C, cooled to a temperature of 20 ° C, the resulting shenite is filtered (K2.3O4G Mg SO46H, jO), Shenit decompose
