- •
Zinc recovery from spent batteries is achieved by leaching with ammonium chloride.
- •
Ammonium chloride leaching is selective for zinc, against manganese and iron.
- •
More than 70% of Zn recovery can be attained.
- •
Final leach liquors contained near 6 g/L Zn and usually less than 0.1 g/L Mn.
