2017-3-27 · 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. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below).

Phytomining & Bioleaching By Lucy Patterson (Sophie's
2018-7-20 · 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?

1998-9-1 · 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 ...
