- •
It is very difficult to extract Pb from lead bearing waste glass as Pb atoms are fixed firmly in the glass network.
- •
The Pb in leaded glass can be extracted in NaOH solution after mechanochemical reduction with metallic iron as additive.
- •
The mechanochemical reduction process with iron follows the scheme: [PbO3] + Fe → Pbmod − O + FeO.
- •
A novel hydrometallurgical process for recovering Pb from lead bearing waste glass in alkaline solution is proposed.
