Abstract

In order to have increased utilization of copper during the decoppering process of technical lead in lead refinery in Trepça two samples have been analyzed with the same chemical composition. Furthermore, identical parameters have been used for both samples which are: the quantity of technical lead, the process temperature, the quantity of brimstone loaded, the mixing time and the time of removal of schlicker, and the dismantle of rings formed in the walls of caldron for refinery. After the removal of brimstone schlicker and chemical analyses one calculates the balance of melting phases and decoppering and the scale of copper utilization. The majority of copper is removed from technical lead with the oxide schlicker, one part with the liquation and remaining part by decoppering with brimstone. The paper reflects on increasing utilization of copper in the decoppering of technical lead which is achieved with effective engagement of human factor.
