this species for phytomining was also evaluated and it was proposed that a yield of 100 kg=ha of Ni should be achievable at many sites worldwide with applied fertiliser and adequate moisture. 3. Phytomining for thallium Introduction This subsection reviews phytomining for Tl and presents previously unpublished data on Tl in plants.
Phytomining for nickel, thallium and gold The first phytomining experiments were carried out in California using the Nihyperaccumulator Streptanthus polygaloides and it was found that a yield of 100 kg/ha of sulphurfree Ni could be produced.

ADVANTAGES. DISADVANTAGES. Bioleaching is in general simpler and cheaper to operate and maintain than traditional processes. The bacterial leaching process is very slow compared to other methods. The process is more environmentally friendly than traditional extraction methods.
A major disadvantage of phytoremediation is its relatively slow pace, because it requires several years or even decades to halve metal contamination in soil (McGrath Zhao, 2003). Furthermore, during the process of phytoremediation, a contaminated site is not available for sale or rent, which can cause problems for economic development . The challenge for plant scientists is therefore to improve the .
Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide. ... What are the advantages and disadvantages of phytomining and ... For these reasons, a setup of bioleaching must be carefully planned, since the process can lead to a biosafety ...

Jan 20, 2015· The technique of phytomining involves growing a crop of a metalhyperaccumulating plant species, harvesting the biomass and burning it to produce a bioore. In
What are the advantages of Phytomining? | Yahoo Answers Mar 21, 2012· Phytomining is a new way of extraction of metals of low quality in heavily contaminated metallic conditions. The extraction process is performed by plants, the plants draw up the elements through their roots, it is stored there as the plant grows and then the plant is burned to produce bioore.
Bioleaching Process Mining Fundamentals. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum cobalt, and uranium.
The major drawback of industrial mining is the damage mining operations cause to the environment. Removal of large areas of topsoil can destroy habitats, and the chemicals used in mining operations can leach into the groundwater and pollute the area. Air pollution and radioactive pollution are other possible downsides. Continue Reading.
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,.
The advantages and disadvantages of phytoremediation as compared to other methods of remediation of polluted soils in situ are considered. Examples of successful phytoextraction and phytomining for cleaning up of contaminated soils in Rasteburg (South Africa) and the phytostabilization of technogenic barrens nearby the coppernickel plants in ...

Jan 05, 2012· This is the method mostly used in phytomining. Bioleaching uses bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an efficient, environmentally responsible method.
