We now need to extract the metal from the compound In the case of copper compounds we can displace the copper using iron. Iron is more reactive than copper. We usually use scrap iron which is cheap
اقرأ أكثرPhytomining is an innovative way to recover metals from soils, and it has attracted more and more attention in recent decades (Li et al., 2020; Robinson and Anderson, 2021; van der Ent et al., 2021). In the economic aspect, NMs have been suggested as potential candidates for phytomining because of their high value.

اقرأ أكثرBioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. ...

اقرأ أكثرIntroduction to Bioleaching: Leaching process was first observed in pumps and pipelines installed in mine pits containing acid water. This process was later on employed for recovering metals from ores containing low quantity of the metal. Presently certain metals from sulfide ores and other ores are extracted by employing only leaching method.

اقرأ أكثرBioleaching is also a method of extraction. However it extracts copper compounds from BACTERIA. How do the compounds get there? Like some plants, some bacteria will absorb copper compounds. They then will produce solutions called LEACHATES. These compounds are leached from the solutions using SULFURIC ACID.
