The Mining Innovations for Negative Emissions Resource Recovery (MINER) program’s aim is to support the development of commercial-ready technologies that give the United States a net-zero or net negative emissions pathway toward increased domestic supplies of copper, nickel, lithium, cobalt, rare earth elements, and other critical elements required for the transition to clean energy. The lack of a secure domestic supply of these minerals poses a significant supply chain risk for the United States, especially with regard to batteries, renewable energy generation, and transmission. Meanwhile, the domestic mining industry faces the rapid depletion of high-profit deposits, increased cost of mining and processing, expensive, management, and accumulation of tailings, resulting in an overall reduced return of investment by conventional mining methods. Consequently, the Advanced Research Projects Agency – Energy (ARPA–E) is issuing this Funding Opportunity Announcement (FOA) with objectives to support the development of technology and approaches to: (1) decrease comminution energy by 50% compared to state-of-the-art; (2) increase yield of energy-relevant minerals by reducing unrecovered energy-relevant minerals in the tailings by 50% compared to state-of-the-art; and (3) enabling the negative emissions production of key minerals by sequestering >10 wt.% CO2e per metric ton of ore processed. Four categories have been identified as necessary to achieve these goals and are discussed in detail later: I. Mineral comminution II. Improvements to beneficiation and processing to increase mineral yield III. Carbon negative reactions IV. Sensing, analyzing and enabling carbonation potential and mineralization
