Full Title

Full titles differ between systems:

IPC:

Compounds of aluminium > Aluminium oxide; Aluminium hydroxide; Aluminates > Preparation of alkali metal aluminates; Aluminium oxide or hydroxide therefrom > by treating aluminous minerals or waste-like raw materials with alkali hydroxide, e.g. leaching of bauxite according to the Bayer process > from waste-like raw materials, e.g. fly ash or Bayer calcination dust

CPC:

Compounds of aluminium > Aluminium oxide; Aluminium hydroxide; Aluminates > Preparation of alkali metal aluminates; Aluminium oxide or hydroxide therefrom (C01F7/028 takes precedence) > by treating aluminous minerals or waste-like raw materials with alkali hydroxide, e.g. leaching of bauxite according to the Bayer process (obtaining aluminium oxide or hydroxide from the resulting aluminate solution C01F7/14) > from waste-like raw materials, e.g. fly ash or Bayer calcination dust
