Geometallurgical mapping is a new team-based approach that documents variability within an orebody and quantifies the impact of geology (host rocks, alteration and structure) and mineralogy on grinding, metallurgical response and metal recovery processes. The quantitative, spatially constrained database that results can be readily integrated into 3-D block models and mine planning activities. T...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The publication presents the most recent results of research conducted in metallurgical enterprises which build Polish metallurgical sector. Three main areas of restructuring were tested, that is repair restructuring, development restructuring and adaptation restructuring. For each t...

Recent excavations made by University of Lecce in Piazzetta Epulione and Piazza Castromediano (Lecce) have produced structures and artifacts related to metal-working. Most of the evidence dates back to the Roman period; traces of metallurgical activity can also be traced to the periods preceding and following the Roman period. Iron slags and semi-finished objects have been found in Piazzetta Ep...

Great efforts have been recently made in the world of metallurgy in order to reduce raw material consumption and particularly energy consumption. Although most metallurgical products are produced by the proved procedures of plastic forming, some changes appear owing to the following requirements: – improvement of product quality, – reduction of production costs, – increase of productivity as we...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...
