The solution is clarified by filtering off the solid impurities, commonly with a rotary sand trap and with the aid of a flocculant such as starch, to remove the fine particles. The undissolved waste after the aluminium compounds are extracted, bauxite tailings, contains iron oxides, silica, calcia, titania and some unreacted alumina.

Feb 04, 2006· Yes it is right that you can separate by means of dissolving it to water, since sand is not water solouble and it will be easily segregated. However, if you will use water to filter it up IT IS IMPOSSIBLE FOR SUGAR TO BE BROUGHT BACK EVEN BY EVAPORATION as what some people believed above me.
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts.
Bauxite is ore from which aluminium can be extracted. Most bauxite, including Australian bauxites are lateritic, formed by intense weathering of various rock formations. The alumina in lateritic bauxite is mainly in the form of gibbsite, an aluminium oxide trihydrate.

Bauxite. Bauxite was first produced in Guyana in 1917. Until 1971, the industry was totally owned by two major North American integrated multinationals, Alcan and Reynolds. However, the Alcan subsidiary, Demerara Bauxite Company (DEMBA), and the Reynolds subsidiary, Reynolds Berbice Mines, were nationalised in 1971 and 1975, respectively.
The International Association of Dry Cargo Shipowners (Intercargo) has recently published the "Guide for the Safe Loading of Nickel Ore", which aims to explain, through use of a flow chart, how nickel ore can be safely shipped, within limitations, whilst raising awareness of the serious problem of cargo liquefaction.
