BIOMINING AND BIOLEACHING PDF

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. Bioleaching techniques are often more effective than traditional mining applications and can even be used to clean mine tailings sites. There are many types of bioleaching processes, and copper is the most common. A few of the most popular types of bioleaching extract metals from ore by retrieving sulfide minerals using bacteria that receive energy from non-carbon compounds. Direct bioleaching uses minerals that are easily receptive to oxidation to create a direct enzymatic strike using the microorganisms to separate the metal and the ore.

Biomining is the extraction of specific metals from their ores through biological means, usually microorganism. Biomining is done in two steps often called bioleaching and biooxidation.

Bioleaching commonly refers to biomining technology applied to base metals; whereas, biooxidation is normally applied to sulfidic-refractory gold ores and concentrates.

The biomining methods are affordable, nontoxic, effective, and likewise environment pleasant. Utilizing biotechnology, efficiency of biomining can also be extended with the aid of genetically modified microorganisms. Please log in to get access to this content Log in Register for free.

Bioleaching Definition & Process

Biomining is the process of using microorganisms microbes to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them to dissolve in water.
