Title : The management of slag and lead with slag in port-piri furnace


The paper analyzes technologic process depending on percentage of lead (Pb) in agglomerate and theoretical and real proportion of production of technical lead and slag. Data presented rely on the work of Water-Jacket furnace, and they emerge as a result of theoretical and experimental studying about the amount of the slag and the percentage of lead in the slag. During the technological process analyses of lead production we researched to increase the technical lead amount produced and the reduction of the lead amount in the slag. Through the amount of slag and the technical lead produced we aimed to optimize the lead percentage in a load as well as the parameters of the technological process with an economical and environmental stability. During the calculations we identified the optimal percentage of the lead (Pb) in agglomerate which enters in the process of reductive melting in the Water-Jacket furnaces in “Trepçë”, which amount of the lead is the cause to increase technological capacities.

Key Words: cargo, lead, slag, gases


Professor Ahmet Haxhiaj was entitled PhD by University of Prishtina, Faculty of Mining and Metalurgy, with topic "Intensify and Optimize the Reductive Process of Melting the Lead Agglomerate in Port-Piri Furnace" in 2003.  In 1989 he finished post-graduate studies at University of Zagreb, Faculty of Metallurgy, Sisak. He studied Metallurgy Science and presented a master thesis in "Materials and Heat Balance in Port-Piri Furnace". In 1978 graduated in the topic "Indium Composition in Products and Inter--products of Lead and Zinc, and Seperation Process of Extracting Indium in Trepça. He currently lectures in the Department of Metallurgy and Materials, Faculty of Geoscience, University of Mitrovica and Faculty of Applied Arts at University of Peja. He published more than 42 papers and is a member of the Alb-shkenca board. Since 2016 is the Editing Chief on IJMPEM "International Journal Minerals Processing Extractive Metallurgy. In 1983-1993 he worked in the Zastava laboratory in Peja në thermal processing and was the manager of four projects in this field. In 1978-1983 he worked in the Lead Metallurgy in Zveqan, Trepça.
