  • Phytostabilization Of Mine Tailings In Arid And Semiarid

    Mar 01, 2008 Arid and semiarid soils are often saline, as evaporation rates exceed rainfall and natural salts originate from saline rainfall, unweathered minerals, and fossil salts. 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 ...

  • Geochemical Exploration For Gold In Temperate Arid Semi

    In this chapter we examine how geochemical techniques can be utilized in the exploration for different types of gold mineralization, the specific signatures of which must be identified in the various sampling media rock, soil, etc. used for exploration. The geochemical signature of gold mineralization depends upon several parameters, particularly the style of mineralization in question and ...

  • Plant Growthpromoting Bacteria For Phytostabilization Of

    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 ...

We tested whether ryegrass facilitates Ni, Fe, and Mn uptake by Alyssum . whether co-cropping with ryegrass affects Alyssum yield, and whether Alyssum hyperaccumulator and non-hyperaccumulator species can benefit from co-cropping.

  • Mining In Ecologically Sensitive Landscapes Csiro

    Mining in Ecologically Sensitive Landscapes explores the interface between geology and botany, and mining and conservation. Many areas of unusual geology that contain ore-bearing bodies also support unique ecological communities of plants and animals. Increasing demand to exploit rich mineral deposits can lead to a conflict between mining and conservation interests in such landscapes.
