In this investigation, two electrorefining processes, by using acidic and alkaline electrolytes, have been compared to determine the most significant results of both methodologies.
Effect of lithium-ion batteries on lead recycling As the Li-ion battery industry has increased into more automotive and stationary battery markets, these batteries have made it to the feed stream for secondary lead smelters.
Metals of lead and some lead alloys, lead oxide, nickel and cobalt were recovered from exhausted battery by combined hydrometallurgy and pyro metallurgical method. The spent batteries were dismantled and leached in hot 2M and 5M nitric acid. The unleached fraction was heated with sodium carbonate to produce lead oxide.
Usually, spent lead-acid batteries are separated in lead recycling plants by dismantling and sorting into four fractions: lead paste, metallic fragments, waste acid, and plastic case (Worrell and Reuter, 2014; Zhang et al., 2019). The processing of lead paste is relatively complex because it contains refractory lead sulphate.
