Tellurium is a silvery, brittle metal with a typical metallic luster, usually obtained as a grey powder. In the molten state, it strongly corrodes metals such as iron and copper. Tellurium is very rare in the Earth's crust, but abundant in space. It is sometimes found in its natural form, but is more often found with gold or other metals in ...

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.

1.3 Tellurium. Tellurium (Te) is a metalloid included in the same group as oxygen, sulfur, selenium and polonium. It has been used as catalyst and pigment for ceramics, in metallurgy as an additive to other metals, in glass optical fibres for telecommunications, as well as in magnetic disk and solar panel manufacturing.

Blister copper is refined by an electrolytic process to removes impurities that include tellurium, silver, gold, and platinum. 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 ...

3.3. Selective reduction of gold in PGM solutions. The classic process involving reduction of gold to metal from chloride solution is a simple and effective process that is well suited to batch operation. A large number of reagents have been used, namely hydrazine, SO 2 gas, oxalic acid, bi sulfite, sucrose and others.

Refining Gold with Sulphuric Acid. Pure silver is readily attacked by strong hot sulphuric acid of SG 1.815, or about 90 per cent, strength. The reaction which takes place may be represented as follows: 2Ag + 2H2 SO4 = Ag2 SO4 + 2H2O + SO2. Silver sulphate so produced is very soluble in the strong acid, when it is hot, as little as one …
