Copper telluride slag from copper smelting process is an important source of tellurium (Te). In this work, an efficient and economical hydrometallurgical process for extracting Te from copper telluride slag was proposed. First, H2SO4 and NaClO3 were demonstrated to be effective for separating Te and Cu, and the leaching efficiency of …

In molten form, tellurium is corrosive to copper, iron and stainless steel. It has high melting point about 449.51 o C and boiling point is 988 o C. Its chemical symbol is Te. Tellurium atomic number is 52 and atomic mass is about 127.60 g/mol.

C145 Tellurium is classified as a free-machining copper. The copper telluride precipitations in the microstructure affects the cutting chips into short pieces, thus enabling a much higher machining speed than with pure copper. Copper 145 Tellurium has a machinability rating scale of 85%, compared to pure copper of 20%, thus longer tool life.

This allows the C109 / CW118C to be machined at a much higher speed with lower tool wear, giving machinists and designers a more cost effective product. Tellurium copper is manufactured by refining, melting and casting the material in to billets for the manufacture of the final product. It is essential that any oxygen is eliminated at this ...
