Physical properties of bauxite. bauxite is typically a soft material with a hardness of only 1 to 3 on the mohs scale.it is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5.
An ore is an impure form of mineral, so it cant be given exact chemical formula. whereas a mineral is pure compoundin general, and can be used to obtain pure elements like metals so it has an exact chemical formula.minerals which can used to obtain the metal profitably are called ores.all minerals are not ores but all ores are essentially ...
In terms of physical properties, bauxite formula has a different composition. what it means is that bauxite contains a mixture of oxides like aluminium hydroxides, hydrous aluminium oxides, and minerals like gibbsite, boehmite and diaspore including some clay minerals.it also contains, insoluble materials namely magnetite, quartz, siderite, hematite and goethite.

A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. minerals are most commonly associated with rocks due to the presence of minerals within rocks. these rocks may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases.compounds that occur only in living beings are ...
The chemical formula of a compound is a symbolic representation of its chemical composition. chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. for example, the chemical formula of water, which is h2o, suggests ...

Formation. lateritic bauxites silicate bauxites are distinguished from karst bauxite ores carbonate bauxites. the early discovered carbonate bauxites occur predominantly in europe and jamaica above carbonate rocks limestone and dolomite, where they were formed by lateritic weathering and residual accumulation of intercalated clays or by clay dissolution residues of the limestone.

Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. the climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.
