Differences between electrolytic lead, crude lead, reduced lead, regenerated lead, and lead concentrate

No.1 electrolytic lead: Pb content not less than 99.994%;

Lead 2: Pb content not less than 99.99%;

Coarse lead: oxidation desulfurization of sulfide lead ore - slag removal - crude lead. The purity of crude lead Pb is between 96% -98%;

Reduced lead: obtained by using waste lead as raw material and remelting it in the furnace. The PB content is usually around 96%~98%, and it can also be used as a raw material for producing electrolytic lead. Recycled lead: The amount of lead used in batteries accounts for a large proportion of lead consumption, so waste batteries are the main raw material for recycled lead. In some countries, the amount of recycled lead accounts for more than half of the total lead production. Regenerated lead is mainly produced by the pyrometallurgical method. For example, when dealing with waste batteries, 8-15% crushed coke, 5-10% iron filings, and an appropriate amount of lime, soda, and other fluxes are usually mixed and melted into coarse lead in a reverberatory furnace or other furnace.

Lead concentrate: After being selected through an economically reasonable beneficiation process, the main useful components of the ore are enriched and become concentrate, which is the final product of the beneficiation plant. The content of the main useful components in the concentrate is called the concentrate grade. The grade of concentrate is sometimes expressed as a weight percentage (such as copper, copper, zinc, etc.), while others are expressed as a weight ratio (such as gold ore in grams per ton). It is an indicator that reflects the quality of concentrate and is also a parameter for formulating the beneficiation process flow.
