Lead thermal metallurgy generates slag, flue dust and refractory waste with high lead and occasionally arsenic and antimony content. Secondary lead production from spent automotive batteries dominates the European lead smelting sector, with over 65% of lead demand met from recycled sources. Slag and flue dust arise from blast or rotary furnace processing of battery plates and grids.
Lead slags typically contain 1–5% residual lead with significant antimony, arsenic and bismuth impurities. Flue dust (10 04 04*) concentrates volatile metals and is classified hazardous due to lead content above 0.1%. Slag from primary smelting of lead-silver concentrates may be further processed by fuming to recover zinc oxide before final disposal.
Battery Directive 2006/66/EC mandates 65% collection rate for automotive batteries, ensuring consistent feedstock for secondary smelters. Processing under BREF for non-ferrous metals requires secondary containment for all slag handling to prevent lead runoff.
Typical Generators
Established valorisation pathways for EWC 10 04 06, ranked by economic value and market depth.
Lead slags are processed in fuming furnaces to volatilise residual zinc as zinc oxide fume, simultaneously reducing lead content to below 0.5%. Resulting slag is used as road sub-base or aggregate after leachate testing. Zinc oxide fume is sold to zinc refinery.
Spent refractory bricks from blast furnace linings are crushed and assessed for residual lead content. Low-lead fractions are recycled as aggregate; high-lead fractions are processed as hazardous waste through stabilisation before landfill or metal recovery.
Flue dust and contaminated refractory containing lead above threshold concentrations are disposed to hazardous landfill under 1999/31/EC. Stabilisation with Portland cement reduces lead leachability to meet WAC limits (<5 mg/L Pb, <2 mg/L As) before landfill acceptance.
These are the established routes for EWC 10 04 06. Which one your stream qualifies for depends on its composition, volume and region.
