B. Panic Physical and Mathematical Modeling of Phenomena Proceeding with Gas – Powder Two Phase Flow through Moving Packed Bed in Metallurgical Shaft Furnaces
A lot of metallurgical processes take places in shaft furnaces, where reacting gas carrying powders flows up in packed bed of descending metallurgical materials. Gas + powder two phase flow in fixed packed bed has been investigated by author for many years 1 . At present author undertakes the investigations with moving bed. Physical model with glass bed and glass powders was constructed. The ex...
متن کاملOptions of Utilising Steelmaking Dust in a Non-metallurgical Industry
Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...
متن کاملMine / Mill production planning based on a Geometallurgical Model Mining Mineração
The Pau Branco mine supplies two blast furnaces with iron ore lumps, and currently, charcoal consumption for pig iron production accounts for 47% of the blast furnaces’ operational cost. A geometallurgical model is presented to support an economic study considering reserve volumes, product quality, and operational costs based on the metallurgical performance of different iron ore typologies. Sa...

متن کاملReconstructing the Geomagnetic Field in West Africa: First Absolute Intensity Results from Burkina Faso
We present absolute geomagnetic intensities from iron smelting furnaces discovered at the metallurgical site of Korsimoro, Burkina Faso. Up to now, archaeologists recognized four different types of furnaces based on different construction methods, which were related to four subsequent time periods. Additionally, radiocarbon ages obtained from charcoal confine the studied furnaces to ages rangin...
