Five critical metals.
One factory floor.

THE PROCESS

We designed and built the core equipment from the ground up: our own carbochlorination reactors, molten-salt electrolysis cells, and magnesiothermic-reduction reactors.

THE FIVE-METAL ARCHITECTURE

Five Metals. Two Paths.

For each metal, Duranium designs the carbochlorination reactor around its feedstock and chemistry. Those reactors produce chloride intermediates that follow one of two downstream routes.

ROUTE ONE

Molten-salt electrolysis

Magnesium and aluminum move through Duranium's molten-salt electrolysis cells.

Magnesiothermic reduction

Titanium, zirconium, and hafnium move through Duranium’s magnesiothermic-reduction reactors using magnesium produced on site. Resulting MgCl₂ is recycled to the cells.

Magnesium comes first

because it is both a product and a production input for three other metals.

CLOSING THE LOOP

TURNING CO₂ BACK INTO FEEDSTOCK

Beyond the core production stack, Duranium is developing MMOS,the Molten Materials Oxygen Stripper. The Duranium-designed reactor converts carbon dioxide from carbochlorination back into carbon monoxide for reuse as feedstock.

/01

The core plant works without MMOS

Production does not depend on it. MMOS is an upgrade to a plant that already runs.

It closes the chlorination carbon loop

At scale, MMOS eliminates net carbon emissions from that step.

It materially improves 
plant margins

Carbon that would leave the plant returns to the line as feedstock instead. Additionally bleaching agents are co-produced for sale.
