01 / MATERIAL PROFILE

Follow the route
to a usable product.

Chain focus: By-product recovery and high-purity refining

Gallium is recovered through other mineral-processing chains. Check recovery infrastructure and high-purity refining, not simply the size of a host-resource endowment.

02 / QUESTIONS THAT MATTER

Define the boundary
before the decision.

Specification & unit

Record purity and product form: low-purity metal, high-purity metal and a compound-semiconductor wafer serve different markets.

Recycling question

Is the recoverable stream concentrated manufacturing scrap or dispersed end-of-life devices, and can recovery meet the required semiconductor purity?

Classification context

Listed by Australia and the US; included in the EU critical and strategic lists. Export controls and list status are different questions.

Planning interpretation

The watchpoint, specification caveat and recycling question are editorial due-diligence prompts, not a measured bottleneck score, quote or engineering recommendation.
