Description

Изобретение относитс  к производству глинозема, который  вл етс  источником получени  металлического алюмини The invention relates to the production of alumina, which is a source for producing metallic aluminum.

Известен способ, разложени  алюминатных растворов с полученим глиноэема путем введени  в них затравки гидроокн- си алюмини  при перемешиванш в течение 6О-7О ч при понижении температуры с 6 5-7О до 4О-45с.A known method is to decompose aluminate solutions to obtain alumina by introducing aluminum hydroxide seed into them while mixing for 6O-7O h with a decrease in temperature from 6 5-7 O to 4O-45 s.

OfUJaKO способ позвол ет разлагать алюминатный раствор лишь на 5О-55%, OfUJaKO method allows to decompose the aluminate solution only by 5–55%,

По предлагаемому способу в качестве неорганических реагентов используют фосфорные соединени , например фосфорную кислоту и фосфорные соединеаи  алюмини ,According to the proposed method, phosphoric compounds, for example phosphoric acid and aluminum phosphoric compounds, are used as inorganic reagents.

Оюсоб позвол ет увеличить скорость разложени  алюминатнНгА растворов в 1,5-1,7 раза и степень их разложени  на 2О-25%.гOyusob allows you to increase the rate of decomposition of aluminate solutions in 1.5-1.7 times and the degree of their decomposition by 2-25% .g.

Пример. В алюминатный раство содержащий 133,5 т/п (каустическое отношение cL 1,65) , ввод т затравку - фосфорные соединени  алюмини ,  вл ющиес  отходами при полученииExample. In the aluminate solution containing 133.5 t / p (caustic ratio cL 1.65), seed is introduced - phosphorus aluminum compounds, which are wastes in the preparation

технической п тиокиси ванади  (затравочное отношение 0,01).technical vanadium pioxide (seed ratio 0.01).

Процесс разложени  протекает в течение 48 ч при paBHONfepuoM снижении температуры с65до43С,иза 24, 36 а 48 ч степень . азложени  соответственно составл ет 34,7, 48,4 и 53,4%,The decomposition process takes place for 48 hours at paBHONfepuoM temperature decrease from 65 to 43С, from 24, 36 and 48 h degree. the decomposition is respectively 34.7, 48.4 and 53.4%,

П риме р2,В алюминатный раствор содержащий 133,5 г/п N03 О (каустичесзсое отношение ,75), ввод т затравку - раствор фосфорной кислотьт ;65%-ный) в количестве 1% (в пересчете на 10О%-ную кислоту) от содержани  глинозема в алюминатаом растворе.In recipe p2, In an aluminate solution containing 133.5 g / p N03 O (caustic ratio, 75), a seed is introduced — a solution of phosphoric acid; 65%) in an amount of 1% (in terms of 10O% acid) from the alumina content in the aluminate solution.

За 24, 36 и 48 ч декомпозиции степень разложени  соответственно составл ет 45,5, 51,6 и 53,8% при равномерном снижении TeMHepaTj bi от 65 до 4оСFor 24, 36 and 48 hours of decomposition, the degree of decomposition is respectively 45.5, 51.6 and 53.8% with a uniform decrease in TeMHepaTj bi from 65 to 4 ° C.
