| Abstract: | A novel process to separate selenium and tellurium from precious metal acidic mud was put forward. Leaching rate of tellurium and selenium by alkali leaching is 77.7% and 38.78% respectively. During neutralization process, tellurium content in neutralization slag is 72.88% with tellurium precipitation rate of 98%, and selenium leaching rate is only 4.3%. In reduction process, reduction efficiency is 99% above, and selenium content in crude selenium product is 81.55%. |
