Paradigms Shift for Resource Recovery: Turning Impurities Into Saleable Products

Speaker

Dr Hong Peng

Abstract

This seminar will present research and process development on critical metals recovery from mine waste with a paradigm shift: turning impurities into saleable products. Several industry-driven projects with technology readiness level from bench scale to pilot plant scale will be provided as below:
Mud2Products: Bauxite Residue Utilization Clay2Products: High Purity Zeolites & Rare Earth Extraction
Slag2Products: Value-added Products from Titanium-bearing Steel Slag Invisible
Gold Recovery: Manipulating Iron Precipitation for refractory Gold sulfides
Cavern Salt Recovery: Potassium Resource Extraction from Basin Boree Salt
