>>28505763 (OP)1 metric ton Lithium requires 1,9 million liter of water.
To extract lithium, miners drill a hole in salt flats and pump salty, mineral-rich brine to the surface. After several months the water evaporates, leaving a mixture of manganese, potassium, borax and lithium salts which is then filtered and placed into another evaporation pool. After between 12 and 18 months of this process, the mixture is filtered sufficiently that lithium carbonate can be extracted.
Lithium extraction harms the soil and causes air contamination. In Argentina’s Salar de Hombre Muerto, residents believe that lithium operations contaminated streams used by humans and livestock and for crop irrigation. In Chile, the landscape is marred by mountains of discarded salt and canals filled with contaminated water with an unnatural blue hue. According to Guillermo Gonzalez, a lithium battery expert from the University of Chile, “This isn’t a green solution – it’s not a solution at all.”
