Hydrometallurgical processing of Egyptian bauxite
Hydrometallurgical processing of the beneficiated gibbsitic bauxite was performed by hot leaching with sodium carbonate and lime in an attritor. Aluminium was converted to soluble sodium aluminate low in SiO 2 (0.1%) and the recovery was over 95% for a short leaching duration of 30 minutes at 900 o C.
