Emission profiles and formation pathways of 2,3,7,8
Therefore, it is essential to obtain a full picture of tetra- to octa-CDD/Fs and to better explore their formation mechanisms in secondary copper smelting processes. In this study, the emissions and profiles of 2,3,7,8-PCDD/Fs and non-2,3,7,8-PCDD/Fs were investigated in typical secondary copper smelters.

How a copper smelter works
A smelter that processes secondary raw materials operates in a similar flow. In practice, smelters will often use a mix of primary and secondary materials. The following schematic helps to visualise the main inputs & outputs for the smelting & refining process. -----Last update: August 12, 2021-----References [1] Langner, Bernd E. 2011.
