So metals in their ionic form can easily get detached from their anionic part and get reduced into stable form by using plant/microbial/fungal extract. The secondary metabolites of plant including alkaloids, flavonoids, polyphenols, and terpenoids act as chelator to metal ions and reduce them into zero-valent states.

Sulfuric acid is the most common medium for hydrometallurgical metal extraction; SX processes often report the separation of nickel and cobalt from dilute sulfuric acid solution. This separation is carried out by cation-exchange type reagents. Ion exchange (IX) is used frequently in metal finishing industries for nickel recovery.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

The plant extract acts as a capping agent through a coordination action by capturing the metal ions in the amylose helix on well-defined sites [Citation 9]. The texture of plant leaves and petals acts as a biotemplate and thereby controls the size of the nanoparticles and hinders the agglomeration of particles [Citation 10].
