Monazite Cracking: Alkaline Digestion Kinetics (2D)

A 2D shrinking-core kinetics model of monazite's alkaline (NaOH) digestion: control temperature, NaOH concentration, particle size and stirring intensity, and watch conversion and REE recovery evolve in real time.

This 2D companion drops the 3D factory scene and instead visualizes the actual chemistry of monazite cracking: a shrinking-core kinetic model where each grain's unreacted core shrinks as hot NaOH converts it to a porous rare-earth hydroxide shell, with reaction, product-layer diffusion and stirring all combining through an Arrhenius-driven effective rate constant.

⚙ Under the hood

Shrinking-core model with Arrhenius-temperature and NaOH-concentration dependent reaction and diffusion rate constants combined with stirring-dependent external mass transfer; batch conversion is volume-weighted across a small particle-size distribution.
