Phytomining is the production of a crop39 of a metal by growing highbiomass 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 green39 alternative to existing, environmentally destructive, opencast

Unlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire crop of metalproducing plants, and if global climate change alters weather patterns, the risks associated with establishing a longterm phytomining industry in an area increase.
Phytomining. Phytomining is a method for literally 39farming39 metals by growing hyperaccumulator plants and then harvesting the biomass rich in a particular metal. The potential for phytomining is greatest for nickel because of the occurrence of vast areas of ultramafic soils that are naturally enriched in nickel and occur around the world, Get
Application. Phytoremediation may be applied to polluted soil or static water environment. Examples where phytoremediation has been used successfully include the restoration of abandoned metal mine workings, and sites where polychlorinated biphenyls have been dumped during manufacture and mitigation of ongoing coal mine discharges reducing the impact of contaminants in soils, water, or air.

There are practical limits to main variables that control its economic feasibility are the metal price, the plant biomass, and the highest achievable metal content of the plant .Metal values range from about 15 000 000 t 1 for platinum to about 600 t 1 for lead. At these extremes, a plant with a biomass of 20 t ha 1, such as B. coddii, would need to contain
Why does one burn with a bright white light and the other simply go black What happens in phytomining Read it too In phytomining plants are used to remove the metal from a low grade ore The plants are then burnt to give an ash that contains a fairly high proportion of the metal compound What does phytomining rely on .
Phytomining involves growing plants on top of low grade ores. The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions. These ions are leached from the ash using sulfuric acid. Scrap iron can then be used to displace the copper from the leachate. Bioleaching involves bacteria which feed on the

The most important part of photosynthesis occurs in the chloroplasts. These small photosynthesis factories buried within the leaves house chlorophyll, a green pigment secreted in the chloroplast membranes. Chlorophyll absorbs a wide range of the spectrum of sunlight, giving the plant as much energy as it can for its reactions. The primary
How Does Phytoremediation Work Environmental Sciences Essay. Phytoremediation is the use of living green plants for in situ risk reduction andor removal of contaminants from contaminated soil, water, sediments, and air. Specially selected or engineered plants are used in the process.
