Title:
METAL LEACHING METHOD USING LINKING BETWEEN BIOLEACHING AND ADSORPTION
Document Type and Number:
WIPO Patent Application WO/2021/172718
Kind Code:
A1
Abstract:
The present invention relates to a metal leaching method using linking between bioleaching and adsorption, the method adsorbing and recovering metal cyanide ions generated through bioleaching, thereby increasing metal leaching efficiency. The present invention uses an adsorbent so as to adsorb metal cyanide ions generated during bioleaching and removes same, thereby reducing the concentration of metal cyanide ions that can act as toxic substances to microorganisms during a process, and thus the present invention increases the survival and growth of microorganisms in a bioleaching solution, and thus can continuously leach metal from metal-containing waste.
