Critical Mineral Mining

Read Issue
Trends
Introduction from the editors

Dear Colleague,

In this issue of Trends, we provide several articles on the topic of critical mineral mining.

Our first article gives an overview of the importance of critical minerals to the United States (US) mining industry and the current regulatory landscape.  The second article discusses the limited information available about rare earth elements and their potential risks to human health.  The third article examines the ecological challenges posed by critical mineral mining and ways to mitigate potential impacts.  Our fourth article explores deep-sea mining of critical minerals as an alternative to land-based mining in the face of expanding global demand.

Gradient contributors to this Trends issue include Drs. Leonard Ancuta, Steven Boomhower, Tim Verslycke, and William Dowd; Meghna Swamy, M.S.; Jerry Hu, M.S.; David Dodge, M.S., DABT, CIH; and Sarah Zahn, M.S.

We hope this issue of Trends provides you with a detailed update on the rapidly changing topic of critical mineral mining.

Yours truly,

Kurt Herman, M.Eng., P.G., and Chris Long, Sc.D., DABT
