Phytostabilization of Mine Tailings in Arid and Semiarid Environments ...

In mine tailings operations within arid and semiarid environments, saline groundwater is often used in the beneficiation process, which becomes hypersaline as it is recycled throughout ore processing. As tailings dry, salt crusts form on the surface (Munshower 1994; Newson and Fahey 2003). Therefore, halophytes (salt-tolerant plants) are ...
