Pyrometallurgy Innovation Centre (PYROSEARCH)

FactSage© chemical thermodynamic computer package is developed by CRCT in Montreal (Canada).

The software performs the predictions of thermodynamic equilibria for complex multi-component slag/matte/metal/solid/gas systems. Coupled with other programming languages, it can be used to simulate large-scale industrial processes.

PYROSEARCH develops the proprietary database (UQPY) which covers copper/lead pyrometallurgical processes and contains important minor elements.

Professor Eugene Jak is an official distributor of FactSage software.
