After separation of the residue by filtering, pure gibbsite is precipitated when the liquid is cooled, and then seeded with fine-grained aluminium hydroxide.
If this would be the only requirement, large amounts of kaolinite could be harvested simply by adding gibbsite powder to a silica solution.
However, whereas the brucite structure can be described as a close-packed structure in gibbsite the OH groups on the underside of one layer rest on the groups of the layer below.
The aluminium compounds in the bauxite may be present as gibbsite (Al(OH) 3 ), boehmite (AlOOH) or diaspore (AlOOH); the different forms of the aluminium component will dictate the extraction conditions.
