Including vehicle microchip manufacturing. Here’s an overview of their sources and production:
Gallium
Sources:
- Gallium is primarily obtained as a by-product of aluminium (bauxite) and zinc ore processing.
- The major producers of gallium include China, Germany, Kazakhstan, and Ukraine.
Production:
- World primary production of gallium is relatively small compared to other metals, with estimates around 300 tonnes per year.
- China’s output is the largest, contributing over 80% of the global production.
- The secondary production from recycling of scrap gallium is also significant, adding another 200-250 tonnes annually.
Germanium
Sources:
- Germanium is mainly recovered as a by-product of zinc ore processing and, to a lesser extent, from coal fly ash and recycled materials.
- Key producing countries include China, Canada, Russia, and the United States.
Production:
- The global production of germanium is approximately 130-150 tonnes per year.
- China is the leading producer, contributing around 70-80% of the global supply.
Summary:
- Gallium: Primary production ~300 tonnes/year; significant secondary production from recycling.
- Germanium: Total production ~130-150 tonnes/year.
Both metals are strategically important, and their production is closely monitored to meet the demands of high-tech industries, including the automotive sector for microchip manufacturing.
