Metallurgical process simulation / modeling

Starting from first principles, (mass conservation, charge balance, mass action) models were developed for ion exchange (IX), ion exchange chromatography (IEX), solvent extraction (SX), and resin-in-pulp (RIP).

These models (i.e. UIT’s in-house software) go beyond traditional approaches. They are flexible enough to simulate and optimize a variety of process-specific tasks. The software was tested in pilot projects and industrial applications (the first started already in the nineties). Good software is not built, it
is grown!

Each task requires its own specific model. The degree of model/ software complexity depends on the real-world system to be modeled, the availability of input data,  the computational resources available, the skill of the user, and the types of questions to be answered.
