Minerals & Metallurgical Processing
The minerals and metallurgy specialisation, built on the platform's reactive and electrolyte models: calcine a carbonate ore, leach a metal into solution, and precipitate a product from an aqueous stream.
What you demonstrate: Can model calcination, hydrometallurgical leaching and reactive aqueous precipitation, and read the off-gas and solution chemistry that prove each step.
Learning is free; issuing this certificate is a one-time paid step ($29 · Pro $19) — Pro members save, Campus included.
Modules (0/3 passed)
Module 1 · Calcination & Thermal Decomposition
Driving CO₂ off a carbonate ore in a kiln: the off-gas signature that confirms complete thermal decomposition.
Assessment: Calcine the limestone feed and confirm the kiln off-gas is ≥95 mol% CO₂ — the signature of complete decomposition to lime. (pass 70%)
Module 2 · Hydrometallurgical Leaching
Dissolving a metal value into an acidic lixiviant: reading the pregnant leach solution with an electrolyte property model.
Assessment: Leach the zinc ore into the acidic lixiviant and confirm the pregnant leach solution (PLS) carries ≥5 mol% dissolved zinc sulfate. (pass 70%)
Module 3 · Reactive Aqueous Precipitation
Precipitating a hydroxide by adding caustic: confirming the reaction by the byproduct salt left in the filtrate.
Assessment: Precipitate zinc hydroxide by adding caustic, and confirm the reaction byproduct sodium sulfate appears in the filtrate (≥1 mol%). (pass 70%)
Capstone
Cross-module capstone
Run the leach–electrowin circuit: confirm the pregnant leach solution carries ≥6 mol% dissolved zinc sulfate and the electrowinning cell evolves ≥95 mol% oxygen at the anode, with a compact flowsheet (≤ 8 unit operations).
