Thus, for example, copper was so abundant 5000 years ago, occurring in pure form as well as in highly concentrated copper ores, that prehistoric peoples were able to collect and process it with very basic technology. As of the early 21st century, copper is commonly mined from ores that contain 0.3% to 0.6% copper by weight.

Phytomining & Bioleaching By Lucy Patterson (Sophie's Sibling)

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?

purification of copper by electrolysis metal extraction

Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper

Why do we extract copper from low grade ores?

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. Then, the copper will be extracted from the leachate by electrolysis or scrap iron.
