costeffective. Among the biological technologies, microbial leaching is the most commonly applied method for extracting solid metallic portion from ewaste, because of its natural ability to transform and convert the compounds to a soluble form (Mishra and Rhee 2014).Mainly three microbial groups
costeffective, microorganisms and plants should be added (either separately or together), which then dissolve cyanides. The combined use of microorganisms and plants is probably more effective than the application of plants or microorganisms only. Concrete proposals of procedures for metals recovery are presented in the following literature ...

Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition.
Bioleaching provides an alternative to more traditional physicalchemical methods. Bioleaching, also known as Bacterial oxidation technology, is the process of using bacteria to dissolved metal instead of chemical solution. Bioleaching produces less pollution and little damage to geological formation, since the bacteria occur there naturally.

Bioleaching does not need high temperatures but it produces toxic. substances, including sulfuric acid, which damage the environment. Processing the metal compounds Iron is more reactive than copper.
These new mining methods can recover metals from low grade ores and waste, for example by phytomining using plants and bioleaching using microorganisms. The big disadvantage of these methods is the speed at which they work much more slowly than conventional 'dig .
