WebTellurium is present in the Earth’s crust only in about 0.001 parts per million. Tellurium minerals include calaverite, sylvanite and tellurite. It is also found uncombined in nature, but only very rarely. It is obtained commercially from the anode muds produced during the electrolytic refining of copper. These contain up to about 8% tellurium. WebTellurium - Purplish crystalline Spiroffite and yellow scaly Tellurite along a vein of native Tellurium.
