Physical and Chemical Properties Bauxite is not a mineral but a rock with minerals in it. It is a claylike substance which is pinkish, whitish or reddish in color depending on the amount and type of impurities. It is soft and, when struck with a hammer, does not produce a metallic sound.
The main components of dry bauxite are alumina (3050 (%)), iron oxide, silicon oxide, and titanium oxide. Fig. 1. Aerial view of Rusal Aughinish Alumina Ltd. plant ... is rich in aluminium minerals oxides, clays and a variety of other insoluble materials. Because of this, its effective molecular weight and relative permittivity may change ...
Theory: The formula for potash alum is K 2 SO 4 .Al 2 (SO 4) 3 .24H 2 O. It is prepared by crystallizing the alum from a concentrated solution containing equimolar amounts of potassium sulfate and aluminium sulfate. It is a colourless, crystalline solid with a sour taste. The crystal of potash alum is octahedral. It is commonly known as ...

The Bauxite wikipedia page shows that Bauxite is a mixture of oxides and hydroxides so the formula you have is a general one and so n can be on of several integers 1 to 3. porphyrin Sep 4, 2016 at 8:47 Add a comment
Bauxite is usually classified according to its intended commercial application,, metallurgical, cement, fertiliser, abrasive, chemical or refractory. The vast majority of the bauxite mined globally is classified as metallurgical and is converted to alumina (Al 2 O 3) for the production of aluminium metal. Some clays and other materials can ...
Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic,
Physical Properties of a Slurry: Since the slurry consists of solid particles suspended in a liquid, the properties of a slurry mixture will depend upon those of the constituents. The density of slurry can be calculated from the following equation: ρ m = 100 / (C w /ρ s) + [ (100 C w) / ρ L ] where:
Potash Alum. Potash alum is a chemical compound widely used as the potassium sulfate dodecahydrate. It is double salt that is used commonly in medicine and the water treatment process. Potash alum is also known as potassium alum or potassium aluminium sulfate. The chemical formula of potash alum is K 2 SO 4 .Al 2 (SO 4) 3 .24H 2 O.
Aluminium hydroxide, Al() 3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and hydroxide is amphoteric,, it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al 2 O 3), the latter of which is also amphoteric.
