Description
The spent lead-acid battery contains 30%~40% (mass) of lead paste, this dataset represents the process of smelting lead paste after desulfurization to obtain crude lead, the process adopted is oxygen-rich bottom blow melting method, the melting temperature is 800-900 °C, the melting process needs to add iron filings and coke, with coke as a reducing agent, to reduce the oxides of lead and antimony, the melted iron filings can be used as an isolation layer, effectively separating molten lead from scum and coating to reduce smoke generation.
This dataset is suitable for the enrichment bottoming process of lead paste in spent lead-acid batteries.
Activity Description
This dataset represents the process of smelting desulfurized lead paste to produce crude lead, including the auxiliary materials used, energy and energy media consumed, emissions of air pollutants, and waste generated.
Process Description
The lead paste, after desulfurization, enters the oxygen-enriched bottom-blowing furnace for smelting.
