Major Mines & Projects | Pastos Grandes Project

Halite is a common mineral within the Salar Pastos Grandes and is mined by digging pools of 4 meter by 1 meter wide and 1 meter. The pools become filled with brine rich in NaCl. The water evaporates at a rate of 6-8 mm/day, concentrating crystalline halite. Each pool is filled with salt in 5 to 6 months and "harvested" with backhoes or loaders.
