Evaporation ponds are large, shallow basins designed to collect and concentrate liquids, primarily water. They are often used in industries like mining and agriculture to manage wastewater or brine. The sun's heat causes the water to evaporate, leaving behind solid materials or concentrated solutions. These ponds are typically lined with materials to prevent leakage into the ground. They play a crucial role in processes such as the extraction of minerals like lithium and potash, as well as in the treatment of industrial wastewater. Proper management of evaporation ponds is essential to minimize environmental impacts.
