Method for preparing metal leaching from waste printed circuit board using bioleaching-adsorption combined system

摘要

The present invention relates to a metal leaching method using a linkage between bio-leaching and adsorption in which metal recovery efficiency is increased by adsorption recovery of metal cyanide ions generated through bio-leaching. Since the present invention adsorbs and removes metal cyanide generated during bio-leaching with an adsorbent, it is possible to lower the concentration of metal cyanide ions that act as toxic substances to microorganisms during the process. This allows for continuous metal leaching from metal-containing waste.
