Fast Metals is treating waste with more waste to extract critical minerals

Fast Metals raised $4.3 million in pre-seed funding to scale its mineral recovery process.

The company uses an additional waste stream and chemicals to extract titanium, aluminum, rare earths, and scandium from red mud.

A commercial test contract is already lined up with Metalox.

If successful, the approach could turn a major industrial waste into a source of critical materials for clean energy and advanced manufacturing.
