Comparative life cycle assessment of copper and gold recovery from waste printed circuit boards: pyrometallurgy, chemical leaching and bioleaching
Printed circuit boards (PCBs) make up a substantial amount of electronic waste (e-waste) generated annually. Waste PCBs contain high quantities of copper and gold in comparison to natural ores. As such, āurban miningā of waste PCBs to recover these metals is of commercial interest. In…
