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]
The lease covered an area of 59 square kilometres to a depth of 1,600 meters in the Bismarck Sea to extract essential resources for a period of 20 years. Nautilus sought to extract a total of 1.3 tons of materials, including 80,000 tons of high-grade copper and 150,000 to 200,000 ounces of gold sulphide ore over the course of 3 years. [7]
In June 2021, the Republic of Nauru partnered with The Metals Company to extract deep-sea minerals, driven by the need for renewable energy to support its energy sector [127]. While deep sea mining could provide vital resources, its extraction requires significant energy and capital, and may cause environmental and social impacts on the island.
Water extraction plant alongside the flooding River Dove near Egginton, England, UK. Water extraction (also known as water withdrawal, water abstraction, and water intake) is the process of taking water from any source, either temporarily or permanently, for flood control or to obtain water for, for example, irrigation.
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.
Evaporation ponds are used to extract lithium from underground brine solution. The extracted Lithium is then used to make ion batteries. [5] [3] Mines use them to separate ore from water. The ore can be sold for use in different industries. [3] Potash evaporation ponds are used to extract potassium from the mineral rich solution
To limit the environmental impact of returning the brine to the ocean, it can be diluted with another stream of water entering the ocean, such as the outfall of a wastewater treatment or power plant. With medium to large power plant and desalination plants, the power plant's cooling water flow is likely to be several times larger than that of ...
The term was popularized through Sustainable Development Goal 14 which is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of the goal is to " Conserve and sustainably use the oceans, seas and marine resources for sustainable development ".
