Event Title

Opportunity for the exploitation of useful metals from the slags of blast furnace in lead metallurgy in the Trepça complex through the Electrothermic process

Session

Energy Efficiency Engineering

Description

The slags of blast furnaces in lead metallurgy is a mixture of different oxides, but apart from the various oxides in the slime, the sulfur of metals, dissolved gases in it as well as the metals in the free state are also dissolved. In the composition of the slags enter these metals: Pb, Zn, Cu, Cd, Bi, As, Sb, Ge, Tl etc.

Therefore, exploitation of the useful elements of the slags is in correlation with the new requirements for rational use of raw materials on one side and for environmental protection on the other and together affect the overall lead yield economy.

In lead metallurgy from the blast furnace exceeds about 80% Zn and about 18-20% Cu, 1-2% Pb, about 8-10 g Ag/t as well as rare metals: In, Cd, Se, Tl , Ge etc. The amount of slags deposited by lead metallurgy is about 3x106 t, therefore based on its quantity and its chemical and mineralogical composition, it is an important material for obtaining the most useful metals while the remaining material can be used in the construction industry.

The Electrothermal process is more prospective than the Fjuming and Welc process, in the technical and technological level, so its application is reasonable in this aspect.
