In phytomining, metal is extracted from a crop of plants that absorb metal ions through their roots. in bioleaching, metal is extracted from bacteria that extract metal from an ore. electrolysis is a process used to separate metals from their compounds. there are advantages and disadvantages associated with each method of extracting metals. Introduction the application of bioleaching of metal sulfides (ms) and its understanding have evolved over the last decades. the mobilization of metal cations from often almost insoluble minerals in ores by biological acidification, oxidation, and complexation processes is referred to as bioleaching, and its application is termed biomining, being now a worldwide established geobiotechnological. Bioleaching is another method that can be used to extract metals economically from low grade metal ores. certain types of bacteria for example thiobacillus ferrooxidans are used in bioleaching . these bacteria feed on sulfide minerals present in low grade copper ores , the bacteria produce a watery solution called a leachate which contains copper ions (cu 2 ) through their metabolic processes.

Novel metal extraction approaches such as phytomining and solvometallurgy are also being developed and appear suitable for critical metal extraction from mining and processing wastes. these methods, while shown to be scientific valid, require further development and large scale testing before they can be fully utilised as metal extraction technologies at a commercial scale in the mining industry. In order to extract copper, we can use extraction techniques such as phytomining and bioleaching. these extraction techniques are less harmful to the environment. extracting metal compounds phytomining. phytomining uses plants. in order to extract copper, phytomining uses plants to absorb copper compounds from the ground.
