Research in the Andes examines rock glacier dynamics for mining industry

When it comes to mining for copper and gold, prospectors will move mountains to make it happen. As in, physically dig up the rock, extract the precious metals and move the debris elsewhere.

In the chilly high altitudes of the Andes Mountains, however, what may look like part of a mountain can in fact be a huge, frozen block of rock fragments and ice. When some of that ice melts in the spring, these so-called “rock glaciers” become a valuable source of water for local populations. (more…)

Many of the metals needed to feed the surging global demand for high-tech products, from smart phones to solar panels, cannot be replaced, leaving some markets vulnerable if resources become scarce, according to a new Yale study.

In a comprehensive analysis, a team of researchers from the Yale School of Forestry & Environmental Studies (F&ES) evaluated how all 62 metals or metalloids on the periodic table of elements are used in consumer products, and the extent to which each of those metals could be replaced if reserves dwindle or supplies become unreliable.
