    The two most common minerals of germanium are argyrodite and germanite. Argyrodite is the mineral in which Winkler first discovered germanium. Germanite contains about 8 percent germanium. Most germanium today is obtained from zinc ores. When those ores are treated to obtain zinc metal, some germanium is produced at the same time.
