Germanium: Recycling

• Little recycling from postconsumer scrap

• 25-35% of total Ge used from recycled scrap

• Infrared optics: 30% production from recycled

material

• Fibre optics: 60% recycled material; recovery from fibres 80%; 0.3-1 g

GeO2 per km cable

• Electronics, solar: 50% waste accumulation, recycled

• Polymerization catalysts: 10-70 ppm in PET bottles, no recycling of Ge

possible

Key aspect

Development of a new research topic at BGR:

World-wide raw material potentials for metals of strategic

economic importance to secure a future supply to the German industry

► Characterisation of complex non-conventional deposit types for an

identification of new potentials for high-tech metal supply

(process-oriented research, trace metal distribution, exploration indicators)

► Potential for high-tech metals in mine residues

► New technologies for extraction of trace metals (e.g., using bio-leaching)

Availability and new potentials for mineral resources

Securing the supply of raw materials in the EU – current initiatives

Indium enrichment in marine sulfides

Natural resources(ores, concentrates)

Enhanced recoveryof by-product metals from ore (e.g., indium from zinc ore)

Development of non-conventional deposit types for high-tech metals

Conclusion, High-Tech Metals

• Germany is dependent on the world markets• According to the geology: no shortages for high-tech metals• Shortages caused by the marked situation

country concentration, geostrategic risks, conflict minerals• High-tech metals are mostly by-products (co-elements);

their production depends on the production of major elements (like Pb, Zn, Cu)• Technical realisation of the production of co-elements by metallurgical

treatment (e.g. Ge from coal ash) is needed• Development of non-conventional deposit types (marine mineral resources,

oxydized ores)• Low recycling rates
