Описание предложения The laboratory from Latvia has successfully completed several international biotechnology projects during which were developed bioreactors for various applications. One of the areas where bioreactors may be applied is bioleaching. Bioleaching is the extraction of metals from their ores through the use of living microorganisms. This method can be applied for example, to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, cobalt. Alternative extractions involve many expensive steps such as roasting and smelting, which require sufficient concentrations of elements in ores and are environmentally unfriendly. Low concentrations are not a problem for bacteria because they simply ignore the waste that surrounds the metals, attaining extraction yields of over 90% in some cases. These microorganisms actually gain energy by breaking down minerals into their constituent elements. The metal extractor simply collects the ions out of the solution after the bacteria have finished. The company has developed technologies and manufactures laboratory and pilot scale systems of bioreactors for bioleaching. The company offers a commercial agreement with technical assistance providing technology and ensuring effective installation and maintenance of bioleaching bioreactors.
Инновационные аспекты и преимущества • Economical: Bioleaching is in general simpler and, therefore, cheaper to operate and maintain than traditional processes, since fewer specialists are needed to operate complex chemical plants. • Environmental: The process is more environmentally friendly than traditional extraction methods. Less landscape damage occurs, since the bacteria involved grow naturally, and the mine and surrounding area can be left relatively untouched. As the bacteria breed in the conditions of the mine, they are easily cultivated and recycled. • Ore concentration: Bioleaching can be used to extract metals from ores that are too poor for other technologies. It can be used to partially replace the extensive crushing and grinding that translates to prohibitive cost and energy consumption in a conventional process.
