Limelight laser furnace

Laser light provides electrified industrial heat to process iron ore into iron metal, with significant energy savings.

Laser diodes are arrayed to illuminate large areas of material, enabling us to produce large throughputs of iron metal.

Laser heating achieves extremely high temperatures, enabling the thermal decomposition of iron ore into iron metal and oxygen. This innovation reduces costs and the reliance on chemical reducing agents.

Limelight laser furnace: process advantages

Thermal decomposition in our laser furnace optimizes iron production, eliminating the need for hydrogen or other chemical reducing agents. This improves energy efficiency and simplifies operations.

Previous hydrogen-based ironmaking furnaces can only use high-purity iron ore and produce solid iron - since they operate at low temperatures and cannot remove impurities in their reactors. This limits these reactors to 3% of global iron ore supplies. Limelight's laser furnace can convert low grade ore into molten iron, which can be separated from impurities - unlocking the other 97% of the world's iron ore supply for efficient ironmaking.

Limelight turns iron ore into iron with up to 20% energy savings.
