How is Salt Extracted from the Sea? LEAFtv

Modern sea salt extraction operations typically have a number of these ponds concentrated in one location, separated by levees. Time is usually of the essence in evaporating sea water to extract salt, because an untimely rain can ruin days of evaporation. Therefore, some salt evaporation operations use very large indoor ponds called pans, which ...

Deep sea mining - Wikipedia

OverviewBrief historyResources minedExtraction methodsEnvironmental impactsControversySee alsoExternal link

Deep sea mining is a mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be pr
