Outline of Research at the Start

With the acceleration of the ‘fourth industrial revolution’ and the high importance of ‘safety’ and ‘resources conservation’ perspectives, the ‘sustainable’ and ‘eco-friendly’ supply of ‘precious metals’ (i.e., gold) has become important in the resources engineering field. In line with the trend, this research project proposed ‘development of a novel recovery method for precious metals coupled with extraction using eco-friendly solvent from secondary resources (i.e., electronic wastes)’.

Outline of Final Research Achievements

The main achievements of this project are; (1) successful recovery technique with simple and high efficiency for gold ions from the eco-friendly ammonium thiosulfate solution was newly developed to eliminate the challenges of the limited industrial application by the poor recovery in the system, and (2) to widen the scope of the research, recovery of heavy metal ions from the waste/acid medium by the developed technique was also evaluated, not limited to only gold.

Academic Significance and Societal Importance of the Research Achievements

Currently in metallurgy, the focus is on green mining with non-toxic solution, but the application of the system to industrial mining is elusive so far due to the limited recovery technique. In the project, a simple recovery technique was newly developed and >99% of Au ions can be recovered.
