Critical Minerals

Critical minerals are those that are essential to the economy and whose supply may be disrupted. Demand for many of these minerals has skyrocketed in recent years with the spread of high-tech devices.

Critical minerals are mineral resources that are essential to the economy and whose supply may be disrupted. The 'criticality' of a mineral changes with time as supply and society's needs shift. Table salt, for example, was once a critical mineral. Today, many critical minerals are metals that are central to high-tech sectors. They include the rare earth elements and other metals such as lithium, indium, tellurium, gallium, and platinum group elements.   Read more
