Microbial raw material recycling Startseite Biokonomie

Dec 16, 2013Microbial raw material recycling. While the use of biotechnological methods for the purification of water, soil and air has already been state of the art for quite a few years, the use of microorganisms for the recovery of metal and mineral raw materials from industrial and agricultural waste has also started to attract the interest of scientists.

Recovery of Nickel and Cobalt from Laterite Tailings by

Biomining of sulfidic ores has been applied for almost five decades. However, the bioprocessing of oxide ores such as laterites lags commercially behind. Recently, the Ferredox process was proposed to treat limonitic laterite ores by means of anaerobic reductive dissolution (AnRD), which was found to be more effective than aerobic bioleaching by fungi and other bacteria.
