Copper as well as a number of other commodities are harvested by solution mining methods Water soluble salts such as potash (sylvite) rock salt (halite) thenardite (sodium sulfate) and nahcolite (sodium bicarbonate) are commonly derived from massive sedimentary deposits by in situ methods Most of the sulfur produced in the Gulf of Mexico region is recovered by a solution mining method known as the.The mining practice that uses solutions to extract a desired commodity from an ore deposit where it stands without also extracting the rock is known as solution mining There are essentially two types of solution mining 1) in situ and 2) in place.
