Feldspar, anorthosite and nepheline syenite: Sogn (anorthosite), Stjernøy (nepheline syenite) and Glamsland (feldspar, not in operation).
Graphite: Skaland.
Quartz and quartzite: Gamasfjell (Tana) (quartzite), Kragerø (quartzite), Melkfjell (quartzite), Nasafjell (hydrothermal quartz), Rana (hydrothermal quartz), Drag (hydrothermal quartz) and Svanvik (hydrothermal quartz).
Olivine: Åheim.
Talc: Bårstad and Linnajavri.
Titanium minerals: Tellnes (ilmenite), Engebøfjellet (rutile) and Bjerkreim-Sokndal (ilmenitte).
