A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The salt pans are shallow and expansive, allowing sunlight to penetrate and reach the seawater. Natural salt pans are formed through geologic processes, where evaporating water leaves behind salt deposits.
Brine pools are created through three primary methods: brine rejection below sea ice, dissolution of salts into bottom water through salt tectonics, and geothermal heating of brine at tectonic boundaries and hot spots. Brine rejection: When sea water freezes, salts do not fit into the crystalline structure of ice, so the salts are expelled. The ...

A woman working the salt fields in Kampot. Kampot sea salt storage. Salt production has a long history in the region, but the industry grew rapidly in the 1940s and 1950s. During the Khmer Rouge and the subsequent Cambodian Civil War salt production was nationalized. In 1986, a group of Kampot residents were granted 50 hectares of land by the ...
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 ...
This is a list of countries by salt production. The six leading salt producers in the world, China, the United States, India, Germany, Canada, and Australia, account for more than half of the worldwide production. The first table includes data by the British Geological Survey (BGS) for countries with available statistics.
