Guanma Machinery crude lead refining plant manufacturer, we specialize in engineering high-efficiency smelting systems tailored for secondary lead production and battery recycling operations.ensuring precise purification of crude lead into industrial-grade metal with over 99.985 purity.
Raw Materia & Final Product
What Raw Material Can Our Crude Lead Refining Plant Handle?
Crude lead / hard lead from Lead Smelting Furnace (Pb 92–99 %)
Recycled lead scrap (e.g., used lead-acid batteries, lead cables, lead sheets)
Lead-rich slag and dross from other metal processing
Low-grade lead concentrates
After processing by our Crude Lead Refining Plant, the final products are high-purity lead with customizable purity levels,(≥99.985%) widely used in:
99.99% Pure Lead Ingots: Ideal for manufacturing lead-acid batteries, which are in high demand in the automotive and energy storage sectors.
99.999% Ultra-Pure Lead: Suitable for electronic components, nuclear shielding, and high-precision industrial applications.
Lead Alloys (optional): Customizable alloys (e.g., lead-tin, lead-antimony) for soldering materials, bearings, and construction parts.
Pure Lead Refining Process Flow
Pyrometallurgical Refining Process Flow for Crude Lead
Copper Removal (De-coppering): Crude lead is charged into the refining kettle for copper removal. The resulting copper dross is skimmed off for separate processing. The decopperized lead proceeds to the next stage.
Refining to Remove Arsenic, Antimony, and Tin: The decopperized lead undergoes primary refining to remove arsenic, antimony, and tin. The generated refining slag is removed for separate treatment. The lead, now freed from these impurities, proceeds to softening.
Silver Recovery (Desilvering): The softened lead is treated with zinc for silver recovery. The formed silver-zinc crust is skimmed off for separate processing. The desilvered lead advances to the next refining step.
Zinc Removal (Dezincing): The desilvered lead undergoes secondary refining to remove zinc. The zinc-containing refining slag is separated for further treatment.
Bismuth Removal (Debismuthizing): The preliminarily refined lead is treated for bismuth removal. The bismuth-containing dross is handled separately.
Final Casting into Ingots: The refined lead is fed into the ingot casting machine. The process initiates casting, and ingots are stamped/marked by the coding machine. After this complete refining system, the purity of the refined lead alloy ingots can reach 99.985%.
