Closing the loop
For Aurubis, “closing the loop” means turning customers into suppliers. In the process, copper scrap or production waste that accumulates in the value chain through our customers’ production processes is directly delivered back to us by the customers. This helps us close material cycles.
Both primary and secondary raw materials are becoming more complex, meaning their copper content is decreasing and the levels of other elements and impurities contained in them are increasing.
Compliance means conforming to certain rules. Apart from laws, directives, and other standards, it also refers to internal corporate guidelines (e.g., codes of conduct).
Continuous cast shapes
Products manufactured from endless strands produced in a continuous casting process. Continuous cast shapes are processed into sheets, foils, profiles, and tubes by rolling and extrusion.
Continuous cast wire rod
Semifinished product produced in a continuous process and used for the fabrication of copper wire.
Hardened melt that forms in the converter during the smelting process. Like natural stone, it can be further processed.
Quality product of the copper tankhouse (copper content: 99.99 %) and the first marketable product in copper production.
A product resulting from the processing (enriching) of copper ores, the Aurubis Group’s main raw material. Since copper is found almost exclusively in ores, in compound form, and in low concentrations (usually below 1 % copper content), the ores are enriched in processing facilities into concentrates (copper content of 25 to 40 %) after being mined.
Surcharge for high-quality cathodes, which are used for the production of continuous cast wire rod and continuous cast shapes, among other products.

This organization publishes the GRI Standards, which are the standards and indicators for sustainability reporting. The GRI Standards are established internationally as a framework for voluntary sustainability reporting.
ILO Core Labour Standards
The Core Labour Standards of the International Labour Organization (ILO) of the United Nations comprise four basic principles: upholding freedom of association and the right to collective bargaining, eliminating forced labor, abolishing child labor, and eliminating discrimination in respect of employment and occupation. These are found in the eight fundamental ILO Conventions, which are referred to as the ILO Core Labour Standards.
A by-product of copper production in the refining process. Formed using sand from iron that is chemically bonded to copper concentrates and recycling raw materials. Mainly used in the construction industry as granules/sand or in lump form.
An international standard that establishes the criteria for setting up and monitoring companies’ environmental management systems. A company can receive proof of a functioning environmental management system (certification) through an external expert.
An international, intersectoral standard that regulates the requirements for and implementation of companies’ occupational health and safety management systems. It replaces the OHSAS 18001 standard.
An international standard that establishes criteria for initiating, operating, and continuously improving an energy management system. The objective of the standard is to steadily improve companies’ energy-related performance. Energy-intensive companies have to be certified in accordance with EMAS or ISO 50001 to be eligible to receive concessions on the levies under the German Renewable Energies Act.
Key performance indicator; a parameter that can be used to measure a company’s performance in a certain area.
Kayser Recycling System, a modern recycling plant in Lünen for the treatment of a wide range of copper-bearing secondary raw materials.
Life cycle analysis
Observes and calculates the ecological impacts of a product during its entire lifetime, from the raw material source to disposal.
Method for calculating indirect CO2 emissions (Scope 2). CO2 emissions that are related to the production of bought-in electricity or energy of other kinds are measured using average emission factors for the region where the company is located. See also “market-based.”
London Bullion Market Association (LBMA)
An important trading market for gold and silver independent of the exchanges. The gold and silver ingots traded through the LBMA have to fulfill certain quality requirements.
London Metal Exchange (LME)
The most important metal exchange in the world, with the highest turnover.
Lost time injury frequency rate (accident frequency).
Method for calculating indirect CO2 emissions (Scope 2). CO2 emissions that are related to the production of bought-in electricity or energy of other kinds are measured using the data of the energy supplier or the purchased product. The emission factor is therefore directly related to the type of energy source. See also “location-based.”
A materiality analysis serves to establish the content of non-financial reports or sustainability reports in general, or is used as the foundation for developing sustainability strategies. During the analysis, the sustainability topics that are especially relevant for the company in question are identified.
Metal yield that a smelter can extract beyond the paid metal content in the raw input materials.
Consist of long- and short-term financial liabilities, less cash and cash equivalents.
Net cash flow
The generated surplus of cash and cash equivalents after taking into account cash-related changes in working capital. It is available for payments in conjunction with a company’s investing and financing activities.

Primary copper production
Production of copper from copper concentrates.
Fee for the processing of copper cathodes into copper products.
The REACH regulation has been in force in the European Union since 2007. REACH stands for “Registration, Evaluation, Authorisation and Restriction of Chemicals.” The objective of the regulation is to record all material flows in the EU.
Materials in a closed-loop economy. They arise as residues from production processes or during the preprocessing of end-of-life products and rejects.
Return on capital employed is the ratio of EBIT to capital employed as at the balance sheet date. It describes the efficiency with which capital was utilized during the reporting period.

This term refers to the inclusion of environmental, social, and corporate governance-related criteria in investment decisions in the financial sector. The objective of sustainable finance is to promote long-term investments in sustainable business activities and projects.
An electrochemical process, the last refining stage in metal recovery, takes place in the tankhouse. For copper, anodes and cathodes are hung in a sulfuric acid solution (electrolyte) and connected to an electric current. Copper and baser elements (e.g., nickel) are then dissolved from the anode in the electrolyte. Copper from the solution is deposited on the cathode with a purity of 99.99 %. Precious metals (e.g., silver and gold) and insoluble components settle as “anode slimes” on the bottom of the tankhouse cell.
Treatment and refining charges (TC/RCs), refining charges (RCs)
Surcharges on the purchase price of metals, charged for turning these raw materials into the commodity exchange product – copper cathodes – and other metals.
