Waste Classification

Copper thermal metallurgy generates slag, flue dust, anode slimes and refractory waste across primary smelting, converting and fire-refining operations. Primary copper smelting from concentrate produces converter slag containing 1–5% copper and significant iron, silica and sulphur values. Anode slimes from electrolytic refining contain gold, silver, platinum group metals and selenium, making them highly valuable secondary products.

Copper slag is generated in large volumes from primary smelting; EU production exceeds 2 million tonnes/year. Slow-cooled crystalline slag contains fayalite and has proven applications as abrasive blasting grit, cement substitute and road aggregate. Granulated copper slag quenched with water produces a glassy material used in concrete as supplementary cementitious material.

Flue dust from secondary smelting (10 06 03*) is classified hazardous due to lead, arsenic and antimony content from mixed scrap feeds. Environmental controls under IED require afterburning and wet scrubbing for dioxin and furan control when processing mixed copper scrap containing chlorinated plastics.

Disposal & Valorisation Routes

Established valorisation pathways for EWC 10 06, ranked by economic value and market depth. Slag processing and aggregate use is the primary route.

Slag processing and aggregate use

Primary

Copper slag is slow-cooled and crushed to produce abrasive grit or used as cement substitute at up to 40% clinker replacement ratio. End-of-waste status applicable in many member states for slag meeting EN 12457 leachate standards. Copper-rich slag is returned to smelter for further copper recovery.

Precious metal recovery from anode slimes

Secondary

Anode slimes containing gold (100–5000 ppm), silver (5–30%), platinum and palladium are processed in precious metals refineries via chlorination, solvent extraction and electrorefining. Selenium and tellurium recovered as by-products for solar cell and thermoelectric applications.

Hazardous treatment for contaminated fractions

Backstop

Arsenic-bearing flue dust and contaminated refractory from secondary smelting require stabilisation to meet WAC leachate limits. Portland cement stabilisation reduces arsenic leachability. Treated material disposed to hazardous landfill with 30-year monitoring requirement.

These are the established routes for EWC 10 06. Which one your stream qualifies for depends on its composition, volume and region.

Regulatory Context

Key legislative frameworks governing EWC 10 06 classification, transport, and treatment.

IED 2010/75/EU — Copper smelting BREF

Copper smelters and converters require IED permit. BREF for non-ferrous metals specifies BAT-AELs: arsenic <0.1 mg/Nm³, copper <1 mg/Nm³ from stack. Secondary copper smelters processing chlorinated scrap require dioxin monitoring with BAT-AEL of <0.05 ng TEQ/Nm³.

Directive 2008/98/EC — Copper slag recovery status

Copper slag meeting EN 12457 leachate criteria and structural quality standards can achieve end-of-waste status for use as abrasive grit or construction aggregate. Recovery classification (R5) applies to granulated slag used as cement substitute in clinker production.

REACH Regulation 1907/2006 — Arsenic in flue dust

Arsenic compounds are classified CMR Category 1A; flue dust containing arsenic above 0.1% requires hazardous waste consignment. Anode slimes containing selenium compounds require Safety Data Sheet under CLP Regulation 1272/2008 for any supply.
