🪙 Gold Cyanide Leach: 2D Elsner Kinetics and Tank Cascade Lab

2D companion of the gold cyanide leach simulation: gold grains dissolve in a five-tank cascade following the Elsner diffusion-controlled rate law. Vary cyanide, oxygen, pH, temperature, agitation and grain size and compare simulated recovery with the analytic residence-time model.
