What are the advantages and disadvantages of phytomining?

Answer 1

The advantage of phytomining is that it saves using high grade ores.

However the disadvantage is that this is a long process.

Answer 2

Phytomining is greener than other methods of mining and there is no need to dig huge mines. However, the metal isn't pure so electrolysis has to be used which is expensive. The success of the project depends on growing conditions, and when the plants are burnt CO2 is released.
