What are the main sources of germanium and gallium production?
Germanium and gallium are two rare metals that are used in a variety of applications, including electronics, solar cells, and aerospace. Germanium is primarily obtained as a byproduct of zinc and lead mining, while gallium is produced as a byproduct of aluminum and zinc mining.
The three main sources of germanium production are:
- Zinc ores (sphalerite): Germanium is found in zinc ores, and it is extracted as a byproduct of zinc mining.
- Lead ores (galena): Germanium is also found in lead ores, and it is extracted as a byproduct of lead mining.
- Coal ash: Germanium can be extracted from coal ash, which is a byproduct of coal combustion.
The two main sources of gallium production are:
- Aluminum ores (bauxite): Gallium is found in aluminum ores, and it is extracted as a byproduct of aluminum mining.
- Zinc ores (sphalerite): Gallium is also found in zinc ores, and it is extracted as a byproduct of zinc mining.
