🫧 Froth Flotation Cell — Bubble-Particle Attachment (2D)

This 2D companion trades the 3D version's orbiting stirred-tank view for a side-on cross-section built for reading the mechanism directly: a sparger releases air bubbles at the bottom, sized and spaced by the air-flow control, and each bubble rises through a swirling pulp of amber "valuable" grains and grey gangue particles driven by a rotating impeller. Collector dosage sets how likely a valuable grain is to attach to a bubble it touches — modelling the reagent's job of making the target mineral hydrophobic — while a higher solids percentage raises mechanical entrainment of gangue into the froth, exactly the trade-off a real flotation circuit has to balance. Every bubble that reaches the froth line is counted, so recovery, concentrate grade and mass yield in the HUD come from an actual running mass balance over the simulated particles rather than a static formula.
