Augite Mineral Physical - Optical Properties, Uses and .

The most common pyroxene, augite is named after the Greek word augites, which means "brightness"—a reference to its occasional shiny appearance.Most augite has a dull, dark green, brown, or black finish. Augite occurs chiefly as short, thick, prismatic crystals with a square or octagonal cross section and sometimes as large, cleavable masses.

Abstract. Settling properties of bauxite residue are affected by the form of iron mineral present in the system. The two forms of iron minerals generally found in bauxites are aluminous goethite, α-(Fe,Al)OOH and hematite, α-Fe 2 O 3.Model systems comprising of synthetic goethite and hematite in pure sodium aluminate solutions were used to study reactions representative of those occurring in .

Mining and Refining – Process - bauxite.world-aluminium.org

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
