Metallurgical Thermodynamics and Modelling

The research and teaching at the Metallurgical Thermodynamics and Modeling research group focuses experimental phase equilibria and thermodynamic modeling of metallurgical processes, mainly related to extractive pyrometallurgy and hydrometallurgy from primary and secondary resources.
Aalto University/Metallurgical Thermodynamics and Modelling

Our research areas:

1. Study of chemical reactions, phase equilibria & elemental distribution in existing and new metallurgical processes:

  • Primary ore feeds become leaner and more complex

  • New feeds (E-scrap, WEEE, recycled batteries

2. Development of Process models, calculational tools & thermochemical databases for pyro- and hydrometallurgical processes

3. Study of large industrial processes on a very detailed level through laboratory studies and modeling, Including non-metallurgical processes (e.g. biomass combustion, waste incineration, high-T corrosion)

The Group is responsible for teaching and research in metallurgical thermodynamics. 

The research projects focus on experimental thermodynamics. We utilize experimental techniques, such as equilibration-quenching, EMF measurements, high-temperature furnace treatments to study phase equilibria and thermodynamic properties of metallurgical slags, mattes, and alloys.

We also utilize and develop advanced thermodynamic modeling databases and software for modelling and equilibrium calculations in close cooperation with industrial partners within the field of metallurgical engineering. The industrial projects deal with metal-making processes in the areas of liquid and solid phases (e.g. flash smelting, roasting of sulphides, and salts decomposition by the fluidized bed technology).

The Group is establishing National Centre of Thermodynamics, in cooperation with external partners: we collaborate closely also with universities in Finland, the Nordic countries, South Africa, Canada, China and Indonesia.


Ongoing projects:

Finland-based Circular Ecosystem of Battery Metals, BATCircle

Led by Aalto University, the Finland based circular ecosystem of battery metals consortium (BATCircle in short) aims at improving the manufacturing processes of mining industry, metals industry and battery chemicals, and to increase the recycling of lithium-ion batteries. Its goal is to strengthen the cooperation between companies and research organisations in Finland, and to find new business opportunities.

Symbiosis of metals production and nature, SYMMET

There is currently not enough mining capacity to meet the demand for metals while the use of renewable energy, such as wind and solar energy, and electro-mobility is increasing. The Symbiosis of Metals Production and Nature (SYMMET) project’s objective is to find solutions for the sustainability gap caused by the ever-increasing demand for metals.
