This project will evaluate the potential for cost-effective and technologically viable methods for recovering metals and other valuable materials from the fines generated in mechanically processing e-scrap waste. The initial tasks include procurement of fines from Aurubis & ERI, Inc. and determination of fines content per ton of e-scrap with analysis from sources.
This project will deliver:
- Literature review on current practices – collection, treatment & disposal
- Report on contained metals & materials value
- Economic viability analysis
- Process flow sheet for metals recovery
- Design of equipment and experiments for pilot scale testing
Initial experimental steps involved include:
- Physical characterization: size distribution, composition and phase identification
- Physical separation: density, magnetic (?), eddy-current, electrostatic
- Physico-chemical separation: Flotation
- Chemical recovery: Leaching followed by precipitation, SX, IX, electrolysis, etc.
- Evaluate pyrometallurgical recovery options.
