Platinum Group Metals

Metals such as the platinum-group elements are by definition non-renewable. Thus, there are only techniques which can extend the life of the platinum-group metals, and new technologies can open up new avenues for such pursuits. Fortunately, there are also methods for preserving the metals we have already extracted.
