SEPARATION AND PREPARATION OF Al(OH)_3 FROM ALUMINUM-RICH WASTE RESIDUE

  

Abstract: In order to determine the scheme of separation and preparation of Al(OH)3 from waste residue with high KAlO2 content, solubility for the KOH - KAlO2 - K2CO3 - H2O system was studied. Morcovee some paramaters of the process control were determined, and Al(OH)3 product with a high quality was obtained.
