- •
Thiosulfate–nitrite–copper is a promising silver leaching alternative system.
- •
Thiosulfate concentration determines the copper–ammonia complexes formation.
- •
Antlerite is the main solid residue formed at 0.07 M and 0.1 M thiosulfate.
- •
Stromeyerite is produced on the silver particle at 0.15 M thiosulfate.
- •
85% Ag is leached at 15 min, 45 °C and 0.1 M thiosulfate.
