the demand for its parent metal, copper. Tellurium is typically extracted from copper refined by an electro-lytic process, which is a cost effective technique applied to high-grade copper ores. In this process, tellurium and other impurities, such as gold, silver, and platinum, are concentrated onto, and then removed from, crude copper anodes.

The predominant source of tellurium today is from anode slimes or sludges produced during the refining of copper and lead ores. It takes approximately 500 tons of copper ore to produce 1 pound of tellurium. Tellurium concentrations in porphyry copper deposits vary widely and can be as high as 6,000 ppm Te, but are typically less than 1 ppm Te.

It takes approximately 500 tons of copper ore to produce 1 pound of tellurium. Tellurium concentrations in porphyry copper deposits vary widely and

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.

Tellurium is most often found combined with gold, copper and lead. Most production is from as a by-product of refining of these metals, particularly copper. The supply of tellurium varies depending on the quality of the ore it's recovered from. Processing plants may

Tellurium was discovered in gold-bearing ores by Müller von Reichenstein in 1782 and was given its name (after tellus, earth) by Klaproth in 1798. It is still only found in combination with other metal ores like gold and copper. Properties. Crystalline tellurium is a silvery metal with a typical metallic lustre.

World Resources: Data on tellurium resources were not available. More than 90% of tellurium has been produced from anode slimes collected from electrolytic copper refining, and the remainder was derived from skimmings at lead refineries and from flue dusts and gases generated during the smelting of bismuth, copper, and lead-zinc ores.

Tellurium is widely used in metallurgy (separate metals from their ores) in iron, stainless steel copper and lead alloys. It has high efficiencies for solar cell electric power generators. Tellurium is added to lead to improve its strength and resistance to corrosion.

Tellurium 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.

Tellurium is currently recovered as a byproduct of nonferrous metal mining, principally from the anode slimes associated with electrolytic refining of copper. In copper ores, tellurium forms stable crystalline compounds (called tellurides) of gold, silver, bismuth, mercury, platinum and palladium that tend to accumulate in residual ore fluids.

Tellurium, which is used in metal alloys, semiconductors, and in the solar energy field, is recovered as a primary resource from only two locations in the world, and currently about 85% of global production of tellurium comes as a byproduct of copper mining through a process called electrolytic refining.

Once tellurium is concentrated in this manner, it is directed onto copper anodes and then removed. To extract about 2.2 pounds (1 kilogram) of tellurium requires the treatment of 1,000 tons of copper ore. Commercial-grade tellurium has a purity of 99.5% but higher grades of purity are also available. Producing a more refined grade of tellurium ...
