Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-967-8 | CAS number: 67711-91-5 Product of smelting roaster calcines concentrates or cement copper with flux in reverberatory or electric furnaces. Composed primarily of copper and copper, iron and lead sulfides with minor sulfides of other metals.
Guidance on Safe Use
Administrative data
First-aid measures
Inhalation:
In case of exposure to fumes, fine particulates move to fresh air, lay patient down, get medical attention if discomfort persists.
Ingestion:
Rinse mouth thoroughly. Give 200-300 ml water to drink. Do not induce vomiting. Get medical attention if any discomfort continues.
Skin contact:
- Matte, copper- grade 1 is not a skin irritant nor skin sensitizer. Use general hygiene measure for contact with the material: wash with soap and warm water.
- In case of contact with molten product, cool rapidly with water and seek immediate medical attention. Do not attempt to remove molten product from skin because skin will tear easily. Cuts or abrasions should be treated promptly with thorough cleansing of the affected area.
Eye contact:
Matte, copper- grade 1 is not an eye irritant. Use general measures if eye irritations occur. Do not rub eyes. Remove any contact lenses. Flush eyes thoroughly with water, taking care to rinse under eyelids. If irritation persists, continue flushing for 15 minutes, rinsing from time to time under eyelids. If discomfort continues, consult a physician.
General advice:
Get medical attention if any discomfort develops. Seek medical attention for all burns, regardless how minor they may seem. Show this safety data sheet to the doctor in attendance.
Notes to physician: Treat symptomatically. The effects might be delayed.
Fire-fighting measures
Material is non-flammable. Use fire fighting measures appropriate to surrounding materials.
Unusual fire & explosion hazards: Solid metal is not flammable; however, finely divided metallic dust or powder may form an explosive mixture with air. Do not use water on molten metal: Explosion hazard could result.
Specific hazards Fire or high temperatures create: Metal oxides.
Extinguishing media : sand, graphite, dolomite, sodium chlorite
Extinguishing media which must not be used for safety reasons: Do not use water or halogenated extinguishing media.
Special protective equipment for fire-fighters: Self-contained breathing apparatus and full protective clothing must be worn in case of fire.
Accidental release measures
Personal precautions in case of accidental release of fine particulates, powders: Ensure adequate ventilation. Avoid inhalation of fumes, dust.
Environmental precautions : Avoid release to the environment.
Methods for cleaning up:
-Ventilate the area thoroughly.
-Restrict the area to those persons wearing respiratory protection. Do not allow unprotected people into the area until cleanup has been completed.
-Allow spilled material to solidify and scrape up with shovels into a suitable container for recycle or disposal as hazardous waste.
-Collect dust, particulates, powders using a vacuum cleaner with a HEPA filter. Place in a suitable container for recycling or disposal as hazardous waste
-DO NOT empty into drains or waterways .
Handling and storage
The substance is an intermediate to be used under Strictly Controlled conditions. Control and procedural technologies are used to minimize emissions and release resulting exposure.
The material is stored and transported in massive form, thereby seriously reducing the risks for exposure.
The main potential risks occurs during the melting of matte/black copper to produce the anode, blister. The manufacturer has documented at the manufacturing site how strictly controlled conditions are guaranteed. These include:
-Provide adequate ventilation.
-Avoid generation and spreading of dust (use of hoods above smelters and appropriate dust filters).
-Avoid inhalation of dust and small particles and contact with skin and eyes.
-Wear appropriate personal protective equipment (gloves and/or RPE) in area¿s where dusts are present (smelting area and during critical maintenance operations).
-Observe good industrial hygiene practices.
-Perform appropriate monitoring campaigns to demonstrate absence of risks towards exposures of Cu
General measures : Avoid contact with molten material. Do not use water on molten metal.
Avoid contact with sharp edges and hot surfaces
Storage Massive material: Store away from incompatible materials. Store in a cool, dry, well-ventilated place, avoiding contact with heat and acids.

COMPONENTS WITH CRITICAL VALUES THAT REQUIRE MONITORING AT THE WORKPLACE:
-7440-50-8 Copper in accordance to national Level Limit Value
Stability and reactivity
Disposal considerations
Waste from surplus, unused product: recycling into the smelter is to be preferred rather then depositing the waste
