The element is a poor conductor of heat and only a fair conductor of electricity. Tellurium burns in air or in oxygen with a blue-green flame, forming the dioxide (TeO 2).It is unaffected by hydrochloric acid, but either nitric acid or aqua regia (a mixture of nitric acid and hydrochloric acid) oxidizes it to tellurous acid (H 2 TeO 3).It reacts with …

A simple and efficient method was proposed to selectively separate and recover tellurium and bismuth in an acidic leaching solution of tellurium−bismuth ore by Na 2 SO 3 and Fe powder. Then, the selective reduction mechanism was investigated by SEM−EDS, XRD, XPS, ICP-OES, etc. 99.83% Te in leaching solution can be reduced …
