We can extract the copper from this with electrolysis or by a displacement reaction with scrap iron: Cu 2+ (aq) + Fe(s) → Cu(s) + Fe 2+ (aq) Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade ores are increasingly rare.

Phytomining - ScienceDirect

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 ...

Some advantages of bioleaching include: Bioleaching can stabilise sulphate toxins from the mine without causing harm to the environment. Poisonous sulfur dioxide emissions harm the environment and can cause health problems for miners, and bioleaching avoids this process entirely. Bioleaching is more cost-effective than smelting processes.
