“Yes, it is entirely normal for concentrate grades to fall below target specifications during the early stages of a flotation plant's commissioning.Initial periods (often called "hot commissioning") are essentially a shakeout phase where operators must physically synchronize the circuit and calibrate their systems to the specific run-of-mine ore.Typical reasons for lower-than-target grades during this period include:Tuning the Chemistry: Flotation plants rely heavily on exact chemical balances, including frothers, collectors, and pH modifiers. The chemical regimen must be precisely calibrated to the specific physics of the ore being processed.Mechanical Synchronization: Equipment like air blowers, milling circuits, and scraper paddles must be tuned and synchronized.Circuit Stabilization: Operators must adjust the flotation time and slurry density to prevent unwanted waste minerals (gangue) from floating into the concentrate.Industry practice focuses on progressive optimization, steadily refining reagent dosing and parameters to maximize both grade and recovery as the plant stabilizes”
All is going to well and to plans.
