Investment and innovation for secure cmm supply chains building on decades of fundamental materials research, doe has funded targeted critical minerals and materials (cmm) r&d activities for more than ten years, evolving from a focus on rare earth elements to the current focus on the electric eighteen.

National policy and critical minerals list according to a national research council report, a critical mineral is a nonfuel mineral that is essential for use and faces considerable supply chain vulnerabilities For example, silicon is essential for manufacturing computer chips Lithium is essential for manufacturing batteries And rare earth elements are essential. The critical minerals and materials (cmm) program aims to rebuild u.s Leadership in extraction and processing technologies to support an economically, environmentally and geopolitically sustainable u.s

Domestic supply chain for cmm1, 2 — which include rare earth elements and a host of other critical elements — from secondary and unconventional resources After processing, rare earths and other critical materials can then be combined with other materials to form a metal alloy. Executive summary critical minerals and materials are used in many products important to the united states economy and national security Thus, the assured supply of critical minerals and materials and the resiliency of their supply chains are essential to the economic prosperity and national defense of the united states Of the 35 mineral commodities identified as critical in the list1. 40 common minerals and their uses aluminum the most abundant metal element in earth’s crust

Aluminum originates as an oxide called alumina

Bauxite ore is the main source of aluminum and is imported from jamaica, brazil, guinea, guyana, etc.
