- •
Ludwigite is boron containing iron ore and can be used for boron extraction.
- •
Isothermal and non-isothermal reduction of ludwigite/coal pellet was performed.
- •
Volume shrinkage of the pellet highly depends on reduction temperature.
- •
Activation energy for volume shrinkage during isothermal reduction is 276.0 kJ/mol.
