Jun 29, 2007· In their natural habitats this hyperaccumulation most likely serves as a defence against pathogens and herbivores, as demonstrated in many studies (Boyd ... These processes are important in terms of using hyperaccumulators for the phytoremediation or phytomining of metal‐rich soils, because they set the frame that limits the biotechnological ...
Indicative content. Points that may be used in the argument: phytomining conserves supplies of ores; copper will be available for longer as at present rate of use copper ores will run out in about ...
Cards for pupils to create a flowchart on how pure copper is obtained from lowgrades ores via bioleaching and phytomining. Contains: Pictures of each step in the process, a description to link to and differentiated questions. Comments welcome....

Phytoremediation and phytomining: a practical activity; Phytoremediation and phytomining: a practical activity Phytoremediation is the use of green plants to decontaminate soils in situ. Soils can become contaminated from activities such as mining manufacturing. In turn, the copper can be extracted from the plants, known as phytomining.
Hyperaccumulators are being intensely investigated. They are not only interesting in scientific context due to their "strange" behavior in terms of dealing with high concentrations of metals, but also because of their use in phytoremediation and phytomining, for which understanding the mechanisms of hyperaccumulation is crucial.
Phytomining, bioleaching and scrap iron. Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. ... Consider the arguments for and against quarrying limestone in a national park. Posted on 05:03 / 0 comments ...
The oldest methods for removing rock from underground mines were the sledgehammer and wedge and the equally ancient technique of fire setting. In the latter case a fire set up against a rock face would produce thermal expansion stresses the rock would either crumble naturally or could be shattered by water quenching.
Copper(I) complexes. Forming copper(I) complexes (other than the one with water as a ligand) also stabalises the copper(I) oxidation state. For example, both [Cu(NH 3) 2] + and [CuCl 2]are copper(I) complexes which don't disproportionate. The chlorinecontaining complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid.

Large ultramafic areas exist in Albania, which could be suitable for phytomining with native Alyssum murale. We undertook a fiveyear field experiment on an ultramafic Vertisol, aimed at optimizing a lowcost Niphytoextraction crop of A. murale which is adapted to the Balkans. The following aspects were studied on 18m2 plots in natural conditions: the effect of (i) plant phenology and ...
An important step in phytomining operations is the recovery of metal from harvested plant material. In this work, a laboratoryscale horizontal tube furnace was used to generate Nienriched bioore from the dried biomass of Ni hyperaccumulator plants. Prior to furnace treatment, hairy roots of Alyssum bertolonii were exposed to Ni in liquid ...
