    Eolian dispersion of mine tailings in arid and semiarid environments is an emerging global issue for which economical remediation alternatives are needed. Phytostabilization the revegetation of these sites with native plants is one such alternative. Revegetation often requires the addition of bulky amendments such as compost which greatly increases cost. We report the use of plant growth .

    Tailings Management at Mining Sites with HighPressure

    For many mining operations the go-to method of managing tailings is to use a tailings facility or dam. The problem here is that if these dams fail they can cause significant harm to people and the environment putting a hard stop on mining operations and causing businesses to incur major penalties.
