Yellow ochre, FeO(OH)·nH 2 O, is a hydrated iron hydroxide (limonite) also called gold ochre.; Red ochre, Fe 2 O 3, takes its reddish colour from the mineral hematite, which is an anhydrous iron oxide.; Purple ochre is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with a greater average particle size.
Ochre was used in the preparation of the grave and strewn on the burial itself. Slightly over half of the burials – 164 – involved the use of ochre. Among the ochre graves, there were 130 graves entirely strewn with ochre, with greater or lesser intensity, as well as partially ochre-strewn graves, where the red pigment had only

It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process. The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process ...
The ore is chemically broken down with concentrated sulphuric acid. The result is a deposit of iron and titanium sulphate, which is then dissolved in water and boiled to result in the precipitation of the titanium as metatitanic acid and its separation from the iron.
