  • Biomining Wikipedia

    Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.What is Bioleaching?

    After the process, the soil is remediated. [citation needed] Of course many pollutants kill plants, so phytoremediation is not a panacea. For example, chromium is toxic to most higher plants at concentrations above 100 μM·kg−1 dry weight. Mining of these extracted metals through phytomining, is a conceivable way of recovering the material.Bioleaching an overview ScienceDirect Topics,Bioleaching —a biomining process—uses direct metabolism or byproducts of microbial processes to solubilize a metal sulfidic ore or waste into an aqueous solution, and it is used at commercial scale for the extraction of base metals, for example, copper, tin, or zinc [11, 19].
