ClosedLoop Recycling of Copper from Waste ...
This model of copper extraction, combining bioleaching and electrowinning, demonstrates a closedloop method of recycling that illustrates the appliion of bioleaching in the circular economy. The copper foils have the potential to be reused, to form new, high value copper clad laminate for the production of complex printed circuit boards for the electronics manufacturing .

Bioleaching: metal solubilization by microorganisms
· Bioleaching is a simple and effective technology for metal extraction from lowgrade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.

GCSE CHEMISTRY
Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper ( II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.

phytomining, and bioleaching are being developed. These methods avoid traditional mining methods of digging, moving and disposing of large amounts of rock. The damage done by mining can be seen in the picture on the right. With a lot of waste produced the copper ore being mined recently contains less and less copper.

Phytomining involved growing plants in soil containing metals. Harvest the plants then burn them. You can collect the metals from the ash. This method is also used to decontaminate soil that contains toxic metals. Bioleaching relies on bacteria to make leachate solutions rich in these metals which can be electrolysed.
