Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.
