Tantalum is primarily obtained from a mineral called coltan. The mining process can vary depending on the location, but generally involves:
- Extracting coltan ore: This can involve open-pit mining or dredging.
- Crushing and separating the minerals: The coltan is separated from other minerals in the ore.
- Chemical processing: Chemical processes are used to extract tantalum from the coltan.
- Refining: The extracted tantalum is further refined to achieve the desired purity.
