Countries Who Rely on Desalination - WorldAtlas

04/25 · Desalination is the process of purifying saline water to make it fit for human consumption. Of all the water on earth, 97.5% of it is saltwater with only 2.5% being fresh water. However, over two-thirds of the fresh water is trapped in glaciers and ice caps in the polar regions of the globe which leaves only 0.83% of the total water on earth being accessible clean water.

Innovations: How Hydrometallurgy and the SX/EW Process Made

The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a large-scale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.
