Possibilities Of Recycling Of Magnesium And Magnesium Alloys, Zeljko J. Kamberovic
Possibilities Of Recycling Of Magnesium And Magnesium Alloys, Zeljko J. Kamberovic
Zeljko J Kamberovic
In this paper are presented results of experimental investigation of processing of non oil-contaminated metal scrap based on magnesium and its alloys. These are the firs investigations of magnesium scrap recycling in Serbia and Montenegro. Experimental investigations were conducted in laboratory scale and achieved results were verified in industrial scale (Magnesium factory ″Bela Stena″ in Baljevac on Ibar). Experiments included following the influence of preparation of metal scrap on metal extraction efficiency rate.
Development Of Contemporary Procedures For Lead Obtaining, Zeljko J. Kamberovic
Development Of Contemporary Procedures For Lead Obtaining, Zeljko J. Kamberovic
Zeljko J Kamberovic
Contemporary procedures of lead concentrates treatment were in different expansion during last thirty years. All procedures have in common the following: smelting reaction proceeds in solid-gas suspension, melting products are metallic lead and slag, which are leaving electric furnace together. The conditions for production metallic lead and slag in one furnace are determined using thermodynamic analysis of contemporary direct smelting procedures. The characteristics and progress of direct smelting process are determined using oxygen/concentrate ratio, which influences the lead content in slag, sulphur content in bullion and the following metals distribution. The KIVCET and Boliden TBRC are contemporary procedures that found …
Optimisation Of Ferriferous Dust And Mud Preparation Acts From Iron And Steel Production On Purpose Of Returning To Primary Processes, Zeljko J. Kamberovic
Optimisation Of Ferriferous Dust And Mud Preparation Acts From Iron And Steel Production On Purpose Of Returning To Primary Processes, Zeljko J. Kamberovic
Zeljko J Kamberovic
In this paper detailed characterization of ferriferous dust and mud which originated from aglomerization, blast- furnace and converter process in Iron-works Smederevo were shown. Optimization of method peletization was conducted in variably conditions (different moinsture content, changing of time of peletization and type of binder). These palets were submitted to examination of resistance on impact and pressure, and their behavior was confirmed returning in sintering process in semiindustrial conditions. Ideally-technological solution for plant preparation of dust and mud in Iron-works Smederevo was recommanded. That solution should contribute to improvement of techno-economic parametars of aglomeration and blast- furnace process, as well …
