Cobalt is a vital element in many technological applications, which, together with its increasing end-use in batteries, makes it important to quantify its cycle of use. We have done so for the planet as a whole and for the three principal cobalt-using countries - China, Japan, and the United States - for 2005. Together, China, Japan, and the United States accounted for approximately 65% of the cobalt fabricated and manufactured into end-use products (a total of 37 Gg Co). A time residence model…

Illuminating tungsten's life cycle in the United States: 1975-2000.

TLDR
Tungsten is an example of a critical mineral resource where the majority of the United States' supply comes from imports, it has vital uses in manufacturing, and it has a high rate of loss at end-of-life.

The materials flow of cobalt in the United States

An initial evaluation of the flow of cobalt-containing materials in the United States was prepared. The following aspects of materials flow were included: cobalt released as a result of mining and

Multilevel cycle of anthropogenic copper.

TLDR
A comprehensive contemporary cycle for stocks and flows of copper is characterized and presented, incorporating information on extraction, processing, fabrication and manufacturing, use, discard, recycling, final disposal, and dissipation, providing a framework for similar studies of other anthropogenic resource cycles.
