摘要

Tellurium is introduced in primary copper productionCopper production via copper concentratesCopper concentrate and is usually obtained by hydrometallurgical processingProcessing of the anodeAnode slimes. However, the removal of Te from anodeAnode slime in hydrometallurgical processes is often not very effective, so that Te-containing residues remain in smelterSmelter networks. It is therefore necessary to consider Te removal from other materials such as blister copperBlister copper or copper matteCopper matte. For this reason, a literature study was carried out to summarize and compare possible ways of Te removal in the copperCopper industry—apart from anodeAnode slime processingProcessing. For this study public scientific literature as well as patents were used. To compare the different processes, the type and composition of the starting materials, the individual process steps and the Te end products were examined.
