Production cycle:
 de-sliming;
 roasting the slime with obtaining the cinder;
 smelting the cinder to obtain the slag;
 leaching the slag, and conversion the tellurium into the solution;
 electrolysis and forming the telluride solution;
 precipitation of tellurium from the solution;
 filtration and washing the precipitate;
 drying and packing.
Application range:
Tellurium is used in the production of lead alloys with the higher plasticity and strength (used, for instance, at the cable production). The production of the lanthanide tellurides, and of its alloys, as well as of alloys with metal selenides – to produce thermoelectric generators with the highest efficiency (up to 72-78%), and also to make the KPT (cadmium-mercury-tellurium) alloys, which can detect the emission at the rocket launching.
Form and packaging:
The commercial tellurium is produced as powders. The powder-like tellurium has dark-grey or black color and the apparent density no more than 2.9 g\cu cm.
The powder-like tellurium is packaged in plastic bags as per GOST 17811 and placed into boxes according to GOST 5959.
The commercial tellurium is manufactured in compliance with requirements of GOST 17614, brands: T0, T1 and T2.
