To reap the maximum potential of both soil and plant cultivation yields from chosen metal crop, it is necessary to draw conclusions from lab and field tests (Bani et al. 2015; Robinson et al. 2003).In the practice of phytomining, mainly metalliferous plants are used to obtained metals from toxic soils and then either processed into pure metals or kept in the secure facilities …
Advantages of phytomining. Phytomining offers the possibility of exploiting metals from low-grade ores, overburdens, mill tailings, or mineralized soil that is uneconomic by conventional mining methods (Nedelkoska and Doran, 2000). Its effect on the environment is minimal because of the stabilizing action of the plants when compared with the ...

DISADVANTAGES OF PHYTOMINING: Phytomining process extracts low-grade minerals. This process is very slow and time-consuming. Only 50% of metal is extracted through this process. High concentrations of toxic elements can pollute groundwater, which is poisonous to living beings. Toxic chemicals are produced during this process which causes a ...
In phytomining, metal is extracted from a crop of plants that absorb metal ions through their roots. In bioleaching, metal is extracted from bacteria that extract metal from an ore. Electrolysis is a process used to separate metals from their compounds. There are advantages and disadvantages associated with each method of extracting metals.

Some disadvantages of phytomining include the long time it takes for plants to accumulate enough metals, limited plant species that are effective at accumulating metals, …
A disadvantage of phytomining is that the process takes a lot longer than the classic methods. Bioleaching. Bacteria are added in with low-grade ores. The bacteria break down the ores to create a solution rich in copper compounds known as a leachate solution. We can easily extract copper from leachate solution.
Phytomining What is phytomining? This process takes advantage of how some plants absorb metals through their roots The plants are grown in areas known to contain metals of interest in the soil. As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves These parts of the …
Phytomining has several advantages over conventional mining. It offers the possibility of exploiting ore bodies or mineralized soils that are otherwise uneconomic to work, and its effect on the environment is minimal when compared with the erosion caused by opencast mining; the area to be mined may be `ready-vegetated'; a `bio-ore' has a higher ...
