Welcome
Welcome to the Center for Sustainable Separations of Metals, a National Science Foundation Center for Chemical Innovation.
CSSM scientists are developing cross-disciplinary chemistry for greener mining and the efficient recycling of critical metals such as lithium, cobalt, gold, rare earths, tantalum, tellurium, and others. Efforts in the center are focused on the development of new, sustainable metals-processing that produces minimal waste and environmental harm.
