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.
Typical Generators
Established valorisation pathways for EWC 10 06 01, ranked by economic value and market depth.
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.
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.
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 01. Which one your stream qualifies for depends on its composition, volume and region.
