Langbeinite Froth Flotation Cell (2D)

This 2D companion swaps the 3D version's factory-diorama camera for a plain cross-section built for reading the process chemistry directly: ore particles fall into the pulp, bubbles rise from a sparger, and every attachment is decided by an actual Langmuir collector-adsorption isotherm — θ = K·dose / (1 + K·dose) — combined with a particle-size recovery window that peaks near 75 µm, the same shape real flotation size-recovery curves take. Recovery, concentrate grade and mass pull are not scripted numbers; they are totalled from every simulated particle that reaches the concentrate launder or the tailings, so pushing collector dosage or brine saturation too far reproduces the textbook grade/recovery trade-off instead of an animation of one.
