P&ID extraction for mining and mineral processing.
Slurry recirculation drives the controls topology. Every grinding circuit feeds flotation, every flotation circuit feeds a thickener, and water-recovery and reagent make-up weave through every page of a drawing set that runs into the hundreds.
- Classified I/O list with AI, AO, DI, DO per instrument
- Master instrument index across the full drawing set with tag-collision detection
- Equipment list. Mills, cells, thickeners, pumps, filters, conveyors
- Line list with size, slurry pipe spec, abrasion-resistant linings, and service
- Valve list. Knife-gate, pinch, dart, control, on, off, with actuator type
- Cross-page connector matching for circuits spanning dozens of sheets
- Revision comparison for plant retrofits and capital projects
- Slurry pipe specs, rubber-lined, ceramic-lined, abrasion-resistant preserved in the line list as drawn
- Knife-gate, pinch, and dart valves dominate on, off duty. Valve list distinguishes the type rather than collapsing to a generic on, off
- Hydrometallurgy circuits, leach tanks, SX, EW cells carry dense valve schedules. Tag-collision detection runs across circuits
- AS 1100 dialect support reads alongside ISA 5.1 on Australian projects
- Tailings instrumentation, pond level, decant tower, beach monitoring, embankment piezometers feeds dam-safety reporting under GISTM
- Smelter flash-furnace and converter drawings carry refractory-monitoring TC arrays and off-gas temperature profiles
- Comminution circuits, SAG mill, ball mill, HPGR carry vibration, bearing-temperature, lubrication, and lining-wear instrumentation. Grouped on the equipment list rather than scattered across the I/O list
- Tropical and remote-site projects often have IFC drawings that diverge from the as-installed plant. Revision comparison surfaces the delta
- MSHA, US and analogous mine-safety regulators drive ventilation and safety-system documentation
- ICMM standards for tailings management increasingly require structured monitoring datasets
- Provincial environmental regulators, e.g. Ontario MECP audit discharge instrumentation as part of permit reporting
