Bioleaching is the extraction or liberation of metals from their ores through the use of living organisms. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to treat ores or concentrates containing copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.

Sep 20, 2024 · Bioleaching, also called biomining or microbial bioleaching is a biotechnological process that employs microorganisms to extract metal from their ores and the solid metallic waste.

Bioleaching (or biomining) is a process in mining and biohydrometallurgy (natural processes of interactions between microbes and minerals) that extracts valuable metals from a low-grade ore with the help of microorganisms such as bacteria or archaea.

Extraction of metals from low-grade ores by employing microorganism is called as bio­leaching. Large quantities of low-grade ores are produced during the separation of higher-grade ores and are generally discarded in waste heaps. Metals from such ores cannot economically be processed with chemical methods.

Bioleaching is the dissolution of ore or another solid material by chemical reactions catalyzed by microorganisms. It can be differentiated based on the chemical processes described in detail (Glombitza and Reichel 2014). Oxidative bioleaching

The solution is called a leachate and the process is called bioleaching close bioleaching Using bacteria to extract metals from their ores..

Bioleaching is a technique that uses microorganisms to remove metals from ore where traditional extraction methods are not economically viable. This technique is commonly used for sulfide mineral ores, which are the source of numerous valuable metals such as gold, silver and copper.
