Bioleaching and Phytomining

 · Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process - it can take years to extract 50% of the metal from a low grade ore. Energy is needed in the elctrolysis step. Energy is needed in the electrolysis step. Then, the copper will be extracted from the leachate by electrolysis or scrap iron.

Phytomining and Bioleaching

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.

Phytomining

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 ...
