The challenge

Why it matters

Classical flowsheet development takes years for every new feedstock, and most industrial waste streams never get that investment. So tailings, black mass, phosphogypsum and process residues are carried as a disposal cost, with the critical metals still inside them.

The solution

How it works

Corterra 770 turns those streams into ranked, validated recovery routes. Specialised AI synthesises candidate routes from the client’s real elemental profile, with every claim cited to its source; a deterministic physics filter rejects any route that violates the chemistry; a robotic laboratory proves what survives; and actuaries price the risk before capital is committed.
