Lead Oxide Convert To Lead

Nov 29, 2019· If high purity of oxide is necessary, STC suggests a specific process to obtain ultrapure lead oxide from lead battery recycling. The obtained lead oxide can be used as it is in mixture with oxides obtained from battery producers through mills or the Barton process, or can be reduced to metal lead through a thermal reduction and hydrogen.

Highlights A novel process was studied to recover lead as ultra-fine lead oxide from lead paste. The desulphurization rate of lead paste was 99.0% with Na 2 CO 3, NaHCO 3 or (NH 4) 2 CO 3. Around 98% of lead from desulphurized paste was converted to lead citrate precursor. Ultra-fine lead oxide with particle size of 100–500 nm could be obtained at 370 °C.
