Cover: Conceptual illustration of the multifaceted nature of identifying and examining critical minerals. Nonfuel minerals are essential components of most of the products that are used every day including cellular telephones, computers, and electronics. Mineral availability to manufacture these products has to be evaluated in the context of a global mineral market and increasingly complex supply chains. Accurate and timely data on minerals are keys to inform public policy and avoid disruptive fluctuation in mineral supply. Design by Van Nguyen.
