The Mond Process

[TechLord22]

Details

The Mond Process produces Nickel and a Cobalt byproduct from Garnierite.

Products

Main Product: Nickel
Side Product(s): Cobalt

Steps

2 Garnierite (s) + 2 Hydrogen (g) -> Impure Nickel (s) + Steam (g)
NiO (s) + 2H (g) -> Ni (s) + H2O (g)
This step is performend at 473K.

Impure Nickel (s) + 5 Carbon Monoxide (g) -> Nickel Carbonyl (g) + 1 Tetracobalt Dodecacarbonyl (s)
Ni (s) + 5CO (g) -> Ni(CO)4 (g) + 1/12 Co4(CO)12 (s)

Nickel Carbonyl (g) -> Nickel (s) + 4 Carbon Monoxide (g)
Ni(CO)4 (g) -> Ni (s) + 4CO (g)
This step is performed at 493K in a chamber filled with solid nickel spheres.

3 Tetracobalt Dodecacarbonyl (s) -> Cobalt (s) + 3 Carbon Monoxide (g)
Co4(CO)12 -> 4Co (s) + 12CO (g)

Yield

2 Garnierite -> 1 Nickel
6 Garnierite -> 1 Cobalt
