· . An is an accumulation of a particular or more than one . Most are named according to their location for example, Tummalapalle Uranium , India, or after a discoverer e.g. the kambalda nickel shoots are named after drillers.
Mineral - Mineral Rainwater: Each of the -forming processes discussed above involves the transport and deposition of minerals from solution. But solutions can also form by dissolving and removing valueless material, leaving a residuum of less-soluble minerals. developed as residues from dissolution are called residual .
An may also form as a result of several steps of processes that are identical but belong to different periods of geological . are divided into of ferrous, light, non-ferrous, noble, rare, and radioactive metals and of trace elements.

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains …
