Millions for innovation

Four projects 

• Assessment of the melting performance of a new "green" lime product
• Climate-neutral molybdenum processes
• Hydrogen-metallised slag – processing and use – Haggis
• Mineral recovery from residual material from secondary metallurgy

Assessment of the melting performance of a new "green" lime 

The aim of the prestudy is to present a joint development and demonstration trial to test and evaluate the green lime as a slagformer in steelmaking.

The participating companies are SaltX Technology and SMA Mineral. Swerim's Tova Jarnerud Örell, is the project manager.

Climate-neutral molybdenum process

Hydrogen-metallised slag – processing and use – HAGGIS

The aim of the project is to metallise slag from which metals cannot otherwise be recovered, so as to recover valuable alloying elements.

Participants include Uddeholms, Vargön Alloys and Chalmers University of Technology. Pelle Mellin, Swerim is the project manager.

Mineral recovery from residual material from secondary metallurgy – REM

The prestudy will investigate the possibility of increasing the degree of on-site reuse of ladle furnace slag while the same time minimising the amount of virgin lime and dolomite that is used in the EAF process.

The participating companies are Höganäs Sweden, Celsa Armeringsstål and Carbomax. Sara Rosendahl, Swerim is the project manager.
