Many bacteria thrive by reducing Fe (III), ferric iron, to Fe (II), ferrous iron, and Mn (VI) to Mn (II). Thus, these kinds of microbes can be used to leach Fe(III) and Mn(VI) metals from some soils and sediments in order to form a range of materials, such as magnetite, siderite and rhodochrosite. This process, which is called bioleaching, can change sediment structure, as well as create the

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
