What do sunflowers, corn, and cell phones have in common? The element Germanium (Ge). This semi metallic element is widely used in semiconductors incorporated into computers, cell phones, and fiber optic cables.Germanium is also used in smart steering systems and parking sensors because it is transparent in infra red light.
Phytomining of rhenium Phytomining is defined as the uptake and preconcen tration of bioavailable metal species from the environment into the plant biomass in a natural way[9, 10]. Preconditions for rhenium phytomining and production are Find locations with rhenium concentration in
The advantages of the phytomining method of Re recovery from soils proposed by us were illustrated by comparison with the classical methods for Re recovery. Key Words Rhenium, Phytomining, Clover, Lucerne, Environmental friendliness 1 Introduction Rhenium is a rare metal (its occurrence in Earths crust amounts to 7x10 8 %). with unique
As an example of one of these last, you need look no further than the fascinating article titled Phytomining New Method for Rhenium Production to be found in last May's edition of Advanced
Bimetallic platinumrhenium catalysts are employed in petroleum reforming for the production of lead free gaso line, and in a smaller scale, to make high octane hydro carbons like benzene, toluene, and xylenes (Naumov 2007; Polyak 2014a). With an ever increasing demand of Re, current world production is 53 tonne per year, featuring
This idea lead to another related technology, phytomining ( Nicks and Chambers, 1994 ), where the goal of the operation was to extract valuable amounts of TEs from low grade ore bodies.lt;/Pgt;As of June 2014, over 6500 articles have appeared on Web of Science that deal with some aspect of phytoremediation. Phytomining New method for rhenium
Phytoremediation of efficiency of metal by Ficus microcarpa was evaluated through a real scale experiment. The root biomass production of the species varied significantly from 3.68 to 5.43 g because of the spatial heterogeneity of different metals. According to the study it could take 4 93 years to purify excess Cd on the experimental site.
Phytomining can be a completely new means of descent involving precious metals associated with cheap in heavily polluted precious metal weather. The particular descent method is conducted by simply plants, the actual facilities frame the elements through their own origins, it's located there because the place develops and the plant can be
Other metals that are also subjects for phytomining within the scope of the invention, include those of the platinum and palladium families, including palladium, rhodium, ruthenium, platinum, iridium, osmium and rhenium which commonly co occur with Ni and Co. Cultivation of plants which are hyperaccumulators of these metals, in metal rich soils

Phytomining is the production of metal rich biomass that could provide revenue through conversion to energy and recovery of the metal from the plant ash (bio ore) or through green chemistry, where plant borne metals form part of valuable phytochemicals grown for harvest (Hunt et al., 2014).
production of rhenium in 2014 was estimated to be about 44,700 kg, a slight increase from the revised 44,300 kg in 2013 (table 4). Production in the united States, rhenium is produced as a byproduct from molybdenite concentrates that are recovered as a byproduct of porphyry copper molybdenum ore mined in Arizona, montana, new mexico, and utah.
World primary production of rhenium in 2013 was estimated to be about 48,900 kilograms (kg), an 8% decrease from that of 2012 (table 4). Production In the United States, rhenium is produced as a byproduct from molybdenite concentrates that are recovered as a byproduct of porphyry copper molybdenum ore mined in Arizona, Montana, New Mexico, and
Rhenium (Re) is one of the rarest (7 215; 10 8 %) and most widely dispersed elements on Earths upper crust. As a consequence of its scarcity, Re is also one of the most expensive metals in the world market. Re is indeed highly demanded by the aerospace industry for the production of high temperature superalloy turbine blades.
Whatever method is selected to reduce calcium concentration in soil, it should be selected so as to be consistent with the objective of soil phytomining. Addition of Ammonium Fertilizer Generally, high metal concentrations are toxic to plants, and inhibitory of plant growth.
