Do something easy.
Something you can REMEMBER in an exam.

I.e. Harvesting of salt from sea water.

Why make it hard for youself.

Well only the alumina is being turned into Aluminium hydroxide.
So the property is the fact alumina can be turned into aluminium hydroxide and the other stuff can't.

I wouldn't exactly say its solubility. (since the Al(OH)<SUB>3</SUB>, is the soluble part, not the alumina itself)

The other components of bauxite do not dissolve and are filtered from the solution as solid impurities (clarification)

Solubility/particle size i guess.

When then heated to 1050°C, the aluminium hydroxide decomposes to alumina (calcination), giving off water vapor in the process:

mmm...some kind of chemical property.



The problem with your process is that it involves ALOT of chemical properties.
Where the year 11 syllabus focuses on (and defines) mixtures as those that can be separated physically.
