Dec 06, 2019 Naturally occurring tellurium is more rare than gold, and as difficult to find in the earth's crust as any platinum group metal (PGM), but due to its existence within extractable copper ore bodies and its limited number of end-uses tellurium's price is much lower than any precious metal.
ContactDomestic Production and Use: In 2019, no tellurium was produced in the United States. One firm in Texas was thought to export copper anode slimes to Mexico for recovery of commercial-grade tellurium. Downstream companies further refined imported commercial-grade metal to produce tellurium dioxide, high-purity tellurium, and tellurium
ContactTellurium is one of the most rare, stable and solid elements in the earth’s crust. Generally extracted from anode sludge produced during the refining of copper, tellurium is classified as a metalloid or semi-metal meaning it has some properties of both metals and non-metals.
ContactAurubis is one of the world’s largest producers of high-quality tellurium. It is recovered from a variety of primary and secondary raw materials. Through the production processes in our copper smelters, we ensure a continuous supply of tellurium metal and tellurium dioxide.
ContactTellurium in the environment. Tellurium is present in coal at up to 2 ppm. This is probably the major source of this metal, which can be taken by plants from soil. Tellurium in plants can reach level as high as 6 ppm, although few food plants have more than 0.5 ppm and most have less than 0.05 ppm.
ContactTellurium 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.
