Metaalketen

Metaalketen is a term used in Dutch to describe the end-to-end sequence of activities that convert natural metal resources into manufactured metal products. The word combines metaal (metal) and keten (chain). It covers both primary production from ores and secondary production from recycling.

Key stages include exploration and mining; ore processing; smelting and refining to produce base metals; alloying and metal forming (casting, rolling, extrusion); fabrication into components and finished goods; distribution and logistics; and recycling and secondary production at the end of life. The metaalketen thus spans raw material extraction through to finished products and back to secondary metal supply.

Global dynamics: The metaalketen is highly globalized, with different regions specializing in stages of the chain; for example, mining in one country, refining in another, and fabrication in a third. Prices are influenced by supply-demand shifts, energy costs, geopolitics, and currency movements. The chain can be disrupted by mine outages, transport bottlenecks, or policy changes, making resilience a key concern for producers and users alike.

Sustainability and policy: Metal production can be energy-intensive and environmentally impactful, so stakeholders emphasize reducing emissions and water use, improving waste management, increasing recycling, and enhancing material efficiency. The circular economy seeks to secure a larger share of secondary metal supply and promote responsible sourcing, including conflict-free and ethically produced materials.

Common metals involved include iron and steel, aluminium, copper, nickel, zinc, tin, lead, and the rare earth elements used in electronics and renewable energy technologies. See also supply chain management, metallurgy, mining, refining, and circular economy.
