Rare Earth Elements

In 2010 and 2011, Chinese exports of rare earths fell, driven predominately by increasing domestic consumption. China also announced they may require imports by 2014 of certain rare earths, some that are deemed “critical” by the U.S. Department of Energy 1. In a normal market, supply reductions would trigger price increases.

Absorption of Minerals and Metals

Calcium. Calcium is absorbed from the intestinal luman by two distinct mechanims, and their relative magnitude of importance is determined by the amount of free calcium available for absorption: 1.
