  • Bioleaching an overview ScienceDirect Topics

    Bioleaching has been proven to be very efficient in the destruction of pathogenic microorganisms [98]. According to Tyagi et al., the indicator bacterial population is reduced rapidly below the detection limit of 100 cfu/mL during the SSDML process [64]. Similar results were also observed in the ironbased bioleaching process [95]. The

  • Phytomining ScienceDirect

    Phytomining is the production of a `crop' of a metal by growing highbiomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced.Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive,

  • Evaluate the Use of Phytomining and Bioleaching in Metal

    Like phytomining, bioleaching is a useful method for extracting metals from lowgrade ores. This is particularly important for copper, where highgrade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensive.
