OreFlow, a Grinding and Separation Circuit Read as One Balance
In a processing plant a change made in one stage, a finer grind or a different classifier cut, moves every stage after it, and each area reports only its own part. OreFlow keeps the circuit as one balance: every stream carries the mass flow of every mineral in 63 size classes plus water, the grinding circuit is closed (an energy-specific population-balance ball mill with Plitt cyclones), separation runs through flotation banks, a gravity bleed, magnetic drums or desliming, and every unit closes within 1e-9. Twelve authored ore and plant scenarios with 96 variants; the workbench re-solves the circuit in the browser on every control change, and its optimizer and seeded uncertainty re-run there too, beside baked kinetic fits, Sobol sensitivity and five learned surrogates. 52 real ore samples and the hours of an iron-ore plant are workbench sources. Authored scenarios, not a calibrated plant.
