SINTEF, standing as one of Europe’s premier research institutes, has been at the forefront of innovation since its inception in 1950. SINTEF has continually fostered development and progress through research assignments spanning various sectors, both domestically and internationally. With a mission to contribute to societal advancement, SINTEF’s collaborative efforts with the Norwegian University of Science and Technology (NTNU) have resulted in groundbreaking discoveries across the spectrum of natural sciences, technology, and social sciences.
In the realm of raw materials and minerals, SINTEF boosts unparalleled expertise encompassing characterization, processes, metallurgy, chemical properties, and quality definition. Equipped with state-of-the-art laboratories and modern facilities, SINTEF stands ready to tackle the most complex challenges in these domains.
Test facilities – smelting hall in Trondheim, Norway
The smelting hall, situated in Trondheim, Norway, serves as a testament to SINTEF’s rich history and commitment to research excellence. Erected during the 1950s as part of the burgeoning university campus, this hall has been pivotal in conducting a myriad of pyrometallurgical processes. From manufacturing to product development, SINTEF’s involvement spans the entire value chain for industrial metals and metal alloys.
Pilot tests at SINTEF
Participation in the HAlMan project is one examples of SINTEF’s dedication to pushing the boundaries of scientific exploration. Tasked with characterizing raw materials and conducting lab-scale and pilot-scale experiments, SINTEF’s team has significant role in the project.
Within the HALMAN project, about 2 000kg of manganese ore is being processes in the rotary furnace. The furnace can process about 500 kg of material. It has been used for recycling of aluminium dross, processing of red mud, reduction of iron- and manganese-ore.
Furnace body – capacity - 500 kg of material.
Plasma torch – located inside the furnace.
Furnace lid – opening of the furnace for loading and onloading of material.
Hydrogen flame – flaring of unused hydrogen.
Off-gas system – Since only steam is generated, no special procedures are required.
Ignition pole – approximately 3 metres long.
Opening into the furnace.
Protective helmet vizir – from heat radiation.
Heat resistant gloves.
The temperature of the furnace is monitored with a large number of sensors. The operators control the power input to the furnace and the plasma gas which is used in the furnace. The power input can be up to 200kW during normal operation.
1st trial in March 2024
March witnessed the commencement of the first pilot-scale tests within the rotary furnace, marking a monumental achievement for SINTEF and its collaborators. As the project progresses, SINTEF remains steadfast in its pursuit of excellence, driving innovation and shaping the future of raw materials and metallic alloys.
