Extracting minerals from seawater
WebTraditionally, salt was harvested from either solar evaporation ponds or rock deposits. Salt evaporation ponds are shallow, artificial basins designed to extract salt from seawater, salty lakes, or mineral-rich springs through natural evaporation (SF Fig. 2.4). As the water dries up, the salt crystals are harvested by raking. WebJun 8, 2024 · A new scientific paper has outlined a potentially inexpensive way to extract lithium from seawater.
