Phytomining & Bioleaching By Lucy Patterson …
Simply put,PHYTOMINING is a form of EXTRACTION. What does it do? It extracts COPPER COMPOUNDS from the ASH of a burnt plant. By burning . the plant, the oxygen is reacting with copper. This makes COPPER OXIDE . The ash which contains the copper compound is then put through ELECTROLYSIS. How do these compounds get into the plant?

Phytomining and Bioleaching. Metal ores are a finite resource which are in limited supply. New methods of copper extraction exploit waste ores and low grade ores. 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.

Innovations in Copper: Mining & Extraction: Producing ...
The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vil solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

What is used in Phytomining? 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.

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 plant are harvested, dried and burned

2. Economic Viability. If the scale of production is large enough, phytomining could become a cheaper alternative to excavation, but large-scale 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.

How are metals extracted with bioleaching?
Phytomining - How It works When the plants are burned, the ash that is produced contains these copper compounds. Then, the copper will be extracted from the leachate by electrolysis or scrap iron. Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate.
