Chemical extraction

Useful elemental materials are often extracted from compounds rather than found as pure substances. Extraction changes chemistry to obtain the desired elemental material. Depending on the material and feedstock, routes can involve high-temperature reactions, chemical solutions or electricity.

What changes?

Primary aluminium production uses electrolysis after bauxite has been refined to alumina. Copper can follow different processing routes depending on its ore. These examples are not interchangeable recipes: each route has a specific input, equipment and sequence of operations.

What the diagram leaves out

Extraction is distinct from simply melting an existing piece of metal. Primary extraction and scrap remelting enter the chain at different points. Energy sources, reagents, emissions and residues depend on the actual industrial route, so an element name alone does not specify its impacts.

What to look for next

Follow the extracted output into purification, alloying or shaping. Keep the production stage visible when reading statistics.
