Abstract:

The effect of chemical treatment of industrially produced aluminum hydroxide on its seed activity during decomposition and capacity for agglomeration is studied with the aim of preparing sandy alumina in Ural aluminum plants. It is shown that the most suitable reagent for activating aluminum hydroxide is aluminate solution. After two hours of treatment of seed aluminum hydroxide in an alkaline solution at 90°C, the degree of aluminate solution decomposition increases by 4–5%. It is revealed that with the use of production aluminum hydroxide activated in aluminate solution during agglomeration it is possible to reduce the content within it of fraction –45 μm from 25 to 5%. © 2016 Springer Science+Business Media New York
