- •
The acidity and EC of tailings determine the clustering of samples.
- •
Repeated leaching of tailings with water was proposed as a simple test method.
- •
Salt leaching kinetics was well described by a new variant of the shrink core model.
- •
The experimental design provides useful information for the management of tailings.
