Coal, iron ore, gypsum, potash salt and sodium salt are the minerals found in sedimentary rocks. Changes in coordination numbers leads to physical and mineralogical differences; for example, at high pressure, such as in the mantlemany minerals, especially silicates such as olivine and garnetwill change to a perovskite structurewhere silicon is in octahedral coordination.
Strong base for metallurgical industries. Iron from these mines is exported to Japan and South Korea via Vishakapatnam port.
These minerals are found in sands of valley floors and the base of hills. The major examples of these are quartz, the feldsparsthe micasthe amphibolesthe pyroxenesthe olivinesand calcite; except for the last one, all of these minerals are silicates.
Hematite is used in most quantity. The plants that use cattle dung are called Gobar Gas Plants. Represented by a chemical formula. Jurisdiction of the Subcommittee: There are about 20 mineral species that qualify as gem minerals, which constitute about 35 of the most common gemstones.
Due to this, it is important that we conserve the mineral resources. Iron ore, manganese, nickel, cobalt, etc. As a result, conventional infrastructure and transport systems, which are fitted to combustion engines, remain prominent throughout the globe. This iron ore is valuable for the electrical industry because of its excellent magnetic properties.
Crystals are restricted to 32 point groupswhich differ by their symmetry. Decomposition of surface rocks and removal of soluble constituents leaves a residual mass of weathered material which contains ores. It has high carbon, high moisture, and low heating capacity.

Gems are minerals with an ornamental value, and are distinguished from non-gems by their beauty, durability, and usually, rarity.
Examples; gold, silver, tin, platinum, etc.Mining is one of Australia’s most important industries – it helped keep our economy growing while other countries fell into recession, and continues to support jobs and living standards for all Australians.
