Phytomining Exploitation of certain plants' (hyperaccumulators) ability to absorb metal compounds through roots; this is called phyto-Extraction. Plants can then be burned and metal is extracted through the ash; can be used to extract metals from contaminated land.
Oct 31, 2016 · phytomining (uncountable) The planting (and subsequent harvesting ) of vegetation that selectively concentrate specific metals from the environment into their tissues, for the primary or subsidiary purpose of commercial exploitation of the extracted metal.
Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices.
Phytoming and Bioleaching Bioleaching- Advantages Disadvantages of phytomining We can use waste ores, reducing the impact of mining on the environment. Phytomining - How It works Select plants will absorb copper compounds through their roots, and the compounds become concentrated
Phytomining and Bioleaching Metal ores are a finite resource which are in limited supply. Phytomining involves growing plants on top of low grade ores. Bioleaching involves bacteria which feed on the low grade ore and absorb the copper ions.
Phytomining describes the production of a metal crop by using high-biomass plants, which are plants that produce energy or a usable resource when burnt. Phytominers cultivate crops of a specific plant species with high concentrations of a desired metal, harvest the plant and deliver it to a furnace to burn and gather its bio-ore.

Phytomining for metals other than nickel. In a third scenario, the use of hyperaccumulator plants to decontaminate polluted soils [15] (phytoremediation) might result in production of a `bio-ore' of some commercial value to recoup some of the costs of soil remediation.
Phytomining of gold involves extracting gold from soil substrates by harvesting specially selected hyperaccumulating plants. Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals.
Bioleaching is the extraction of metals from ores - Shodhganga. ... BBC - GCSE Bitesize: The future of copper. Research is being carried out to find new ways to extract copper from the remaining low-grade ores, without This method of extraction is called phytomining. Get Price.

Jan 18, 2013 · Answers. Oldest Best Answer: 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 bio-ore.
Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel.

Apr 21, 2014 · 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. This method of extraction is called phytomining. Some bacteria absorb copper compounds.

How copper is extracted by phytomining and bioleaching? Bioleaching uses bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded.
Bioleaching: Making Mining Sustainable The environmental consequences of mining and quarrying are vast, as highlighted in the mining section. Due to an increase in consumerism, heightened dependence on technology, and an overall world population growth, more and more minerals and metals need to be extracted from the earth's surface as shown in Figure 1.

Phytomining is not particular relevant to such resource. Mines in developing countries are often less efficient, so phytomining may be applicable. But the single greatest application may be to small deposits of historic tailings or waste rock with precious metal concentrations greater than 1 g/t.
