Alunite Ammoniacal Leaching — Shrinking-Core Kinetics (2D)

A 2D leaching-reactor lab: an Arrhenius-driven rate constant and the shrinking-core model drive real particle-by-particle conversion as you tune temperature, ammonia concentration, ore particle size and agitation.

This 2D companion swaps the 3D original's factory-walkthrough view for the actual chemistry that drives alunite processing: a shrinking-core model computes how far the reaction front has eaten into each ore particle, with the rate constant itself set by the Arrhenius equation from your chosen leach temperature and ammonia concentration, and by agitation's effect on the boundary-layer resistance around each grain.

⚙ Under the hood

Arrhenius rate constant k = A·exp(−Ea/RT)·[NH₃]^0.5 feeds a shrinking-core conversion model (1−(1−X)^1/3 = k·t/r₀) applied per particle across a size distribution, with agitation thinning the diffusion boundary layer up to ~400 rpm.
