1 · Scoping
We work from your PFD and design data to define the model boundary, the required accuracy, and the decisions it needs to support.
Model Development
A simulation model is only as good as the engineers behind it. Treo builds METSIM® models for mines and minerals-processing operations worldwide — mass and energy balance models that operations actually use to make decisions, built by metallurgical engineers who understand the plants they're simulating.
The approach
Every engagement starts with your process flow diagram. From the PFD we scope the model — unit operations, streams, chemistry, and what questions the model must answer — and give you a defined estimate before any work begins. No open-ended consulting clock.
We work from your PFD and design data to define the model boundary, the required accuracy, and the decisions it needs to support.
Flowsheet construction in METSIM®: mass and energy balances, reaction chemistry, and dynamic behaviour where the problem demands it.
The model is reconciled against your plant data or design basis until its behaviour is defensible, not just plausible.
You get the model, documentation, and a working session with your team. Pair it with training and a run-time licence so the model keeps earning after we leave.
Model audits
We audit existing METSIM® models — assumptions, chemistry, structure and drift against current plant performance — and report what's defensible, what isn't, and what it takes to close the gap. We run a free webinar on exactly this — see Events.
Applications
Crushing and milling mass balances, circuit configuration trade-offs.
Leach, adsorption and equilibrium chemistry — see our insights on cyanide consumption and bio-oxidation modelling.
Pad, stacking and solution management models.
Heat balance and equilibrium modelling for smelting and roasting.
FAQ
It depends on flowsheet complexity and what the model must answer — which is why we scope from your PFD and give a defined estimate before starting. Send the PFD; the scoping conversation costs nothing.
From a few weeks for a focused circuit model to several months for a full-plant dynamic simulation. The PFD scoping sets the timeline alongside the estimate.
Yes — model audits are a standing service, whether the model came from a consultant, an EPCM, or your own team years ago.
Yes. Handover includes the model files and documentation. Your team needs a METSIM® licence to run it — a run-time licence is often enough.
Yes — we deliver model development worldwide, remotely and on-site.
