Metal ores are a finite resource which are in limited methods of copper extraction exploit waste ores and low grade ores.; Phytomining involves growing plants on top of low grade plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions are leached from the ash using sulfuric acid.
Extracting and using metals Iron and aluminium are extracted from their ores in different ways because the metals have different reactivities. Metals are used for different purposes, depending on ...
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.

Jan 18, 2013· 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 . Get Price
Phytomining is the production of a `crop'' 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 `green'' alternative to existing, environmentally destructive, opencast mining practices.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.

BBC GCSE Bitesize: Methods of extracting metals. A secondary school revision resource for Edexcel GCSE chemistry about obtaining and using metals with higher tier.
Jul 25, 2018· If the scale of production is large enough, phytomining could become a cheaper alternative to excavation, but largescale harvesting of plants with concentrations of metal is currently more costly than extracting metals from mines. In the future, as metal prices rise and the yields from mines deplete, this could change.
