Abstract
Изобретение относитс к цветной металлургии, преимущественно к глиноземному производству. Цель изобретени - повышение степени очистки. Дл этого алюминатные растворы, полученные после выщелачивани бокситов обрабатывают реагентом, содержащим оксиды цинка и кадми в массовом соотношении (90-92):(8-10), вз том в количестве 1-2 г/дм3 раствора, с последующим отделением осадка. По сравнению со способом-прототипом это позвол ет существенно снизить содержание в растворе серы и железа. 1 табл.The invention relates to non-ferrous metallurgy, mainly to alumina production. The purpose of the invention is to increase the degree of purification. For this, aluminate solutions obtained after leaching bauxites are treated with a reagent containing zinc oxides and cadmium in a weight ratio of (90-92): (8-10), taken in an amount of 1-2 g / dm 3 of solution, followed by separation of the precipitate. Compared with the method of the prototype, this allows to significantly reduce the content of sulfur and iron in the solution. 1 tab.
Description
Изобретение относитс к цветной металлургии, преимущественно к глиноземному производству.The invention relates to non-ferrous metallurgy, mainly to alumina production.
Цель изобретени - повышение степени очистки.The purpose of the invention is to increase the degree of purification.
Пример 1 (по прототипу). 22 г измельченного боксита, содержащего 1,1% серы, выщелачивают оборотным раствором состава, NaeiO 320,о; AlciO 136,0; 855-1,2 и .проч., при и отношении Т:Ж 1:4 в течение 1,5 ч. Перед вьще- лачиванием в пульпу ввод т ZnO в количестве 5 г/дм. После выщелачивани пульпу охлаждают, разбавл ют гор чей водой, выдерживают дл сгущени при 96-100 С в течение 30 мин и фильтруют осветленньй раствор.Example 1 (prototype). 22 g of crushed bauxite containing 1.1% of sulfur are leached with a circulating solution of the composition, NaeiO 320, o; AlciO 136.0; 855-1.2 and more., With a T: W ratio of 1: 4 for 1.5 hours. Before infusing, ZnO in an amount of 5 g / dm is introduced into the pulp. After leaching, the pulp is cooled, diluted with hot water, kept for concentration at 96-100 ° C for 30 minutes and the clarified solution is filtered.
Пример 2-8. Тот же, что и в примере 1 исходный материал, выщелачивают тем же оборотным раство ,ром, затем охлаждают до 96-100 С, разбавл ют гор чей водой, сгущают при той же температуре в течение 30 мин. Отсто вшийс слив обрабатывают реагентом, содержащим цинк и кадмий в заданных соотношени х, выдерживают и фильтруют.Example 2-8. The same as in example 1, the starting material is leached with the same circulating solution, rum, then cooled to 96-100 ° C, diluted with hot water, concentrated at the same temperature for 30 minutes. The settled drain is treated with a reagent containing zinc and cadmium in predetermined ratios, incubated and filtered.
Услови проведени процесса и полученные результаты приведены в таблице.The conditions of the process and the results obtained are shown in the table.
