HSC Chemistry

Make elements work for you

Every element has its own unique features and properties that determine how it behaves in chemical molecules, species, and processes. Metso HSC Chemistry helps you to understand, control, and master this behavior in chemical processes.

HSC is one of the first software packages to combine versatile chemical, thermodynamic, and mineral-processing features. Thermochemical calculations are useful, for example, when developing new chemical processes and improving existing ones. Because the software enables you to make quick and easy calculations using a standard computer, it has a wide range of educational, industrial, and research applications.

HSC also contains modules for mineral processing and particle calculations, which are integrated with an extensive mineral database. Modules and databases are accessed via a dynamic and fully customizable menu.

The latest HSC Chemistry software contains 24 calculation modules connected to 12 integrated databases.

Need help with a specific chemical issue or calculation? The price and delivery time of the support depends on the case.

Please contact with the following details:

  • Chemical problem,
  • The chemical species and phases,
  • The HSC module which you have used.

Metso will send you a quotation on this basis.


End of HSC7 life cycle

We have ceased support for HSC7 and strongly recommend transitioning to the latest version, HSC10. Please contact for support with your migration process if needed.

Training courses

HSC Training courses help you to get more out of your HSC Chemistry software.

Public - HSC training courses are available annually in different countries depending on demand and HSC user feedback. All participants must bring their own laptop. The latest HSC version with a temporary license for 14 days will be installed in these laptops if needed.

On-Site - HSC training courses can be arranged for companies and universities. These private courses make it easier to focus on such confidential issues and process examples that are important for your organization. Course content may focus on hydro, pyro, or mineral processing applications depending on your requirements and lecturer expertise.

Disk space Minimum 4 GB

Version history

HSC Chemistry history

HSC is one of the first scientific software packages with versatile chemical, thermodynamic and mineral processing features. Timo Talonen created the first HSC module in 1974 to calculate equilibrium compositions in the Outokumpu Oyj sulfur plant gas line. Dr. Antti Roine started HSC digital database development at the Helsinki University of Technology in 1979. Since then, he has managed the HSC development. Development of HSC mineral processing modules was started by prof. Pertti Lamberg in 1990.

The HSC software development was started because there was not such software packages available in 1970s and 1980s. Originally, HSC was developed as an internal tool for Outokumpu Oyj to improve chemical process R&D efficiency. Later on, in 1987, delivery to other companies began.

The development of software and databases has been done in co-operation with several universities including the Helsinki University of Technology (Aalto), Åbo Akademi, Petrozavodsk State University, Luleå University of Technology, University of Kentucky, Montana Tech, the University of Missouri-Rolla, the University of Turku, the University of Jyväskylä, Tallinn Technical University, the Technical University of Lappeenranta, the University of Oulu and the University of Joensuu.

Outokumpu Oyj founded a new company Outotec Oyj in 2006, based on Outokumpu Oyj technology business activities and IPR. The ownership of HSC Chemistry was also transferred to Outotec Oyj.
