- •
Hazard waste from asbestos fiber production with high levels of lizardite and brucite was assessed.
- •
Mg and Fe extraction was assessed using DoE applying Taguchi Method.
- •
Highest Mg and Fe extraction were reached under mild process condition.
- •
Acid excess have not much influence on leaching step.
- •
High dissolution of serpentines was reached during the first 30 min of reaction.
