CMI researchers at Colorado School of Mines conducted the activity for this highlight
Develop a novel approach for decomposition of zinc ferrite at low temperature for the recovery of Zn, Ga, Ge, and In.
- Paper recognized by the Society of Mining, Metallurgy, and Exploration (SME) through the prestigious Arthur F. Taggart award to Vivek Kashyap and Patrick Taylor, Colorado School of Mines.
- Decomposition of pure zinc ferrite at relatively low temperature (550°C) was accomplished, enabling 95% zinc extraction with faster kinetics.
Significance and Impact
Zinc ferrite is a major component of residue from domestic zinc smelting. The Zn in the residue represents a significant potential additional value to the industry, making it economically feasible to recover the trace critical materials Ga, Ge, and In.
Hub Targets Addressed
- Industry adoption of a technology for domestic supply of a metal other than rare earths or lithium.
- CMI grand challenge “Unlocking unconventional resources.”
