The creation of large underground storage facilities for natural gas and liquified petroleum gases has been practiced for many years. Use of cavities obtained through solution of salt for this purpose is a fairly new and novel approach, but has gained increasing importance due mainly to the economics of this type of mining operation as opposed to hard rock …

Solution mining dissolves the salt in water, which is then evaporated to leave behind the crystals. Solar evaporation relies on sun and wind to evaporate water from salt pans, a method commonly used in warmer climates. Geologically, salt deposits are found in sedimentary layers often originating from ancient, dried-up seas or lakes.

7.4.3: Solution Mining. Solution mining is the extraction of the ore through a dissolution process, i.e., we pump a solvent through the ore, the solvent dissolves the constituent of interest, and then we recover and process the resulting liquid, which is known as the solute or pregnant liquor.We can apply this method to in-situ deposits using a borehole mining …

Most salt rocks in China contain a large number of insoluble interlayers, and ISPs are deposited at the bottom of salt caverns after solution mining. For instance, the impurity content of salt rocks in Yunying salt mines is 35 %, and the impurity content of salt rocks in Zhangxing salt mines is 45 %.

During the salt-making season of four to five months, brine flows continuously through these ponds. This is a saturated brine solution, containing as much salt as it can hold, so pure salt crystallizes out of the solution as the water evaporates. Natural chemical impurities are returned to the salt water source. Rock Salt Mining Method

Since 2012, the State has been applying a brine solution (23.3% salt-water solution) to the roads before a forecasted snow event. Known as anti-icing, this practice prevents the formation of frost on pavement, and its implementation has been increasing across New England. Another alternative is the use a 50/50 salt and sand mixture.
