Description
Spent lead-acid battery contain 30%-40% (by mass) of lead paste. This dataset represents the process of smelting desulfurized lead paste to produce crude lead, using oxygen-enriched bottom blowing smelting technology. The smelting temperature ranges from 800 to 900 °C. During the process, iron filings and coke are added, with coke acting as a reductant to reduce lead and antimony oxides. The molten iron filings can serve as a separating layer, effectively isolating the molten lead from the slag and encapsulating it to reduce fume generation.
This dataset is applicable to the oxygen-enriched bottom blowing smelting process of lead paste from 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.
