In page Hydrolysis:

"

Hydrolysis may proceed beyond the first step, often with the formation of polynuclear species via the process of olation.[3] Some "exotic" species such as Sn3(OH)2+4[4] are well characterized. Hydrolysis tends to proceed as pH rises leading, in many cases, to the precipitation of a hydroxide such as Al(OH)3 or AlO(OH). These substances, major constituents of bauxite, are known as laterites and are formed by leaching from rocks of most of the ions other than aluminium and iron and subsequent hydrolysis of the remaining aluminium and iron.[citation needed]
