Decopperization by Utilization of the Filter

The current contribution aims to find the optimal method for removing dramp element copper from molten steel scrap. A special reactive ceramic coating on filter ceramic substrates based on ZnAl2O4 was reported as an effective material for the decopperization process. Therefore, the interaction between the molten copper containing iron Fe-Cu alloys and ZnAl2O4 as well with pure alumina were investigated by applying the sessile drop method at low oxygen partial pressure atmosphere. Furthermore, selenium was found to have a great affinity to copper for forming copper selenide, later on selenium was added to liquid Fe-Cu alloy to verify its decopperizationDecopperization efficiency.
