Tellurium is occasionally found native, but is more often found as the telluride ofgold (calaverite), and combined with other metals. It is recovered commercially from theanode muds that are produced during the electrolytic refining of blister copper. The U.S.,Canada, Peru, and Japan are the largest Free World producers of the element.

Science Quote

'There is no inductive method which could lead to the fundamental concepts of physics. Failure to understand this fact constituted the basic philosophical error of so many investigators of the nineteenth century.'
