India's bauxite deposits are mainly found in the Amarkantak plateau, Maikal hills and the plateau region of Bilaspur-Katni. Odisha was the largest bauxite producing state in India with 34.97 per cent of the country's total production in 2009-10. Panchpatmali deposits in Koraput district are the most important bauxite deposits in the state.
• The term evaporites is used for all deposits, such as salt deposits, mainly chemical sediments that are composed of minerals that precipitated from saline solutions concentrated by evaporation. Evaporite deposits are composed dominantly of varying proportions of halite (rock salt) (NaCl), anhydrite (CaSO4) and gypsum (CaSO4.2H2O).

7. Mining method In India, limestone mines are worked by opencast method. Some mines have well-laid road-cum-rail routes. The large mines are developed by forming benches in overburden and limestone bed. The face length, width and height of the benches correspond to the mining machinery deployed and production schedule. Heavy earth-moving …
3. The principle of supergene ore deposit formation is the concentration of some dilute but valuable component of the primary rock. Two basically different process types may lead to concentration: 1.The valued component is enriched in a residuum, while much of the rock mass is dissolved and carried away. 2.The valued component is dissolved, transported and …

Limestone can also form through chemical precipitation of calcium carbonate in ocean or lake water, or through evaporation in cave systems, leaving behind deposits like stalactites and stalagmites. Overall, limestone forms through either biological or chemical processes involving calcium carbonate in various marine and coastal environments.
