Mineral Study Guide, Bauxite is not a single mineral bauxite is a sedimentary rock of of one or more aluminum-bearing minerals Thus, a single chemical compound does not usually characterize this material (interpreting mineral chemical formulas: atoms, molecules, elements)Petrography and Geochemistry Study of Bauxite in the part ,, Bauxite is the only ore of aluminium, It is an amorphous or clay like substances, the colour of Bauxite is pink but with tin impurities to became brownish It shows oolitic and pisolitic structur It`s hardness is variable but has a low specific gravity of about 26 composition is A1 2 O 3 Bauxite forms a part of Kolli hill in the EasternBarite, Mineral Name: Barite or Baryte Chemical Composition: BaSO 4 - Barium sulfate Color: White, Grey, Brown, Blue, Yellow Streak: White - Clear Hardness: 3 - 35 Cleavage/Fracture: Barite has basal cleavage in 3 directions that are at right-angl oftentimes looks like a rose Crystal Form: Barite has more than one crystal formThe first of many crystal shapes is tabular, which can be ,Bauxite, While bauxite doesn't have many uses alone, the ore found inside the rock has many Aluminium ore is commonly found in bauxite rocks Aluminium is one of the world's most important and useful metals It is used in cars to create engine blocks, cylinder heads and body panels It is also used to make roofing, wall cladding and in window and door ,Uses of Bauxite, 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 mineralsIt also contains, insoluble materials namely magnetite, quartz, siderite, hematite and goethite.
