Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine. The brine may be seawater , other surface water , groundwater , or hyper-saline solutions from several industries (e.g., textile industries). [ 1 ]
It produces 196,000 tonnes of clean salt every year, which is around 0.66% of India's salt production. [3] Salt is produced by evaporation of brine and is mostly managed by the government-owned company Sambhar Salts Ltd. (SSL), a joint venture of the Hindustan Salts Limited and the state government. [4] SSL owns 3% of the eastern lake.
India is the world's most populated country, having surpassed China in 2023. [26] [27] Although population growth in India has slowed, the country's population is expected to grow and hit a peak of 1.7 billion people by 2064. [27] India's replacement level fertility rate is 2, as of 2023. [28]
Inland salt production, using brine from natural brine streams flowing over buried salt deposits that were pumped up from the ground and evaporated using the open-pan technique. [ 4 ] Salt refining , a large-scale salt industry developed in coastal locations and based on a combination of inland salt mining and coastal salt production.
Brine (or briny water) is a high-concentration solution of salt (typically sodium chloride or calcium chloride) in water.In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).
The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries). The worldwide production of soda ash in 2005 was estimated at 42 million tonnes, [2] which is more than six kilograms (13 lb) per year for each person on Earth. Solvay-based chemical plants now produce ...
