Description

Известны способы удалени  железистых соединений из глин и каолинов в виде шликера путем обработки его раствором серной кислоты, с последующей промывкой сырьевой массы.Methods are known for removing ferrous compounds from clays and kaolins in the form of a slurry by treating it with a solution of sulfuric acid, followed by washing the raw mass.

Описываемый способ удалени  железистых соединений из глин и каолинов отличаетс  от известных тем, что шликер в смеси с 10%-ным раствором серной кислоты подвергают автоклавной обработке под давлением от 2 до 3 атм и последующей промывке водой.The described method of removing ferrous compounds from clays and kaolins differs from the known ones in that the slurry in a mixture with a 10% solution of sulfuric acid is subjected to autoclave treatment under a pressure of 2 to 3 atm and subsequent washing with water.

Такой способ удалени  железистых соединений из глин и каолинов позвол ет ускорить технологический процесс, а также снизить содержание окислов железа в глине и каолине и получить сьфье, пригодное дл  производства фарфоровых и фа нсовых изделий.Such a method of removing ferrous compounds from clays and kaolin allows for speeding up the technological process, as well as reducing the content of iron oxides in clay and kaolin, and obtaining cfu suitable for the production of porcelain and faience products.

Предлагаемый способ заключаетс  в следующем.The proposed method is as follows.

Глины и каолины обрабатывают 10%-пой серной кислотой. Раствор серной кислоты добавл ют к глинам и каолинам до получени  шликера консистенции густой сметаны. Затем шликер помещают в автоклав, где его выдерживают в течение 2 час под давлением 2-3 атм. При этом процессе железо переходит в растворимое сернокислое железо. После этого шликер промывают несколько раз водой и сернокислое железо удал ют с промывными водами.Clays and kaolins are treated with 10% sulfuric acid. A solution of sulfuric acid is added to the clays and kaolin until a slurry of thick sour cream is obtained. Then the slip is placed in an autoclave, where it is maintained for 2 hours under a pressure of 2-3 atm. In this process, iron passes into soluble iron sulphate. Thereafter, the slurry is washed several times with water and the iron sulfate is removed with wash water.

Предмет изобретени Subject invention

Способ удалени  железистых соединений из глин и каолинов в виде ш.ликера путем обработки его раствором серной кислоты, с последую, шей промывкой сырьевой массы, отличающийс  тем, что, с целью ускорени  технологического процесса, указанный шликер в смеси с 10/%-ным раствором серной кислоты подвергают автоклавной обработке под давлением от 2 до 3 атм и последующей промывке водой.A method of removing ferrous compounds from clays and kaolin in the form of a liquid by treating it with a solution of sulfuric acid, followed by washing the raw material mass, characterized in that, in order to accelerate the process, the slip is mixed with a 10 /% solution. sulfuric acid is subjected to autoclave treatment under pressure from 2 to 3 atm and subsequent washing with water.
