Mining and mineral processing waste as potential feedstock for critical minerals

Currently, there are nearly 100 legacy mine or mineral processing sites on EPA’s Superfund National Priorities List, and many more abandoned mine land sites throughout the U.S. are in variable stages of remediation.

The purpose of the EMRTAI is to advance technological innovation surrounding the recovery of critical minerals from waste materials at Superfund legacy hard rock mining or metal processing sites.

Many of the technology assessments conducted under the EMRTAI will take place at sites listed on the EPA’s Superfund National Priority List (NPL) and/or use waste materials from sites as feedstock.

The Initiative is slated to run from 2024-2027. The monitoring and recovery of critical minerals from mining-related waste materials can positively impact resource use efficiency and reduce greenhouse gas emissions, environmental impacts, and waste generation.

Critical minerals recovery may expedite the cleanup of legacy mine sites and support the development of a U.S. supply chain for critical minerals.
