Thallium Tl PubChem

The major source of commercial thallium is the trace amounts found in copper, lead, zinc, and other sulfide ores. Several thallium minerals, containing 16% to 60% thallium, occur in nature as sulfide or selenide complexes with antimony, arsenic, copper, lead, and silver but are rare and have no commercial importance as sources of this element.
