[DOE to Invest $975 Million in Critical Mineral Processing] The US Department of Energy (DOE) is set to release a significant funding opportunity announcement aimed at bolstering onshore critical mineral supply chains, with an expected total investment of up to $975 million. This move responds to an earlier executive order by President Trump, which directed the DOE to explore avenues for providing federal funds for critical mineral processing. The core objective of this funding notice is to enhance domestic supply and processing capabilities for rare earth elements, mineral byproducts, and materials essential for semiconductor production such as gallium and germanium. It will also focus on the recycling of critical minerals. Notably, the planned construction of a demonstration plant for rare earth elements, projected to cost around $135 million, will use raw materials sourced from mining and industrial operation byproducts. This initiative not only aims to improve the utilization rate of domestic mineral resources but also to further solidify the US's position in the critical mineral supply chain.
