How to read this list
These metals are byproducts, so supply responds slowly to price. Equity exposure is diluted by the host commodity: aluminium, zinc, copper or molybdenum.
Revenue from the minor metals is typically a small share of company sales, so share prices follow the host commodity first.

Gallium, germanium and byproduct metal stocks: frequently asked questions
Can you buy gallium or germanium stocks?
There are no significant pure-play listed producers. Gallium, germanium, indium, tellurium and rhenium are byproducts of aluminium, zinc, copper and molybdenum, so exposure comes through diversified miners and refiners.
Which companies refine germanium outside China?
Umicore, 5N Plus and Teck are the best-known names, and Korea Zinc recovers it from zinc smelting. Check each company's filings for volumes.
