Technology Description:

Columbia University will develop an integrated hydrometallurgical-electrochemical mining technology to increase energy-relevant mineral yields from CO2-reactive minerals. The technology incorporates an innovative stirred media mill reactor that minimizes comminution energy and improves leaching efficiencies and a new electrochemical refining processes using functionalized interfaces for selective separation of metals. If successful, the technology will enable high recovery of target metals (> 80%) and efficient carbon mineralization (> 90%), while reducing energy input; reduce emissions related to metals mining and production; and provide a domestic source of energy-relevant minerals.

Potential Impact:

The MINER program aims to use the reactive potential of CO2-reactive ore materials to decrease mineral processing energy and increase the yield of energy-relevant minerals via novel negative emission technologies.

Security:

MINER metrics meet the U.S. need for net-zero, commercial-ready technologies that provide energy-relevant minerals for economic and national security.

Environment:

In addition to demonstrating carbon negativity, the proposed technology will quantify and reduce our impact on environmental and human health by addressing ecotoxicity, acidification of air, smog, water pollution, and more.

Economy:

MINER metrics specify increasing the yield of energy-relevant minerals by reducing unrecovered energy-relevant minerals in tailings by 50% compared with state of the art.
