Hydrometallurgical recovery of zinc from electric arc furnace dust was investigated on a laboratory scale, using aqueous sodium hydroxide solution as leaching agent. Special attention paid to the effect NaOH concentration, temperature and liquid/solid phase ratio leachability. It found that all tested factors increased leachability, with maximum efficiency 88% obtained in 6 M at 80 °C 40. The test results confirmed high selectivity In spite this, complete steelmaking has proved be very...

Abstract The present study attempts to apply HE 99.99% pure copper. microstructure of the samples was investigated by both light microscopy and scanning transmission electron (STEM). Additionally, microhardness measured, tensile test made, statistical analysis grains subgrains performed. Based on Kikuchi diffraction patterns, misorientation determined. obtained results show that copper deformed hydrostatic extrusion (HE) is rather inhomogeneous. regions strongly with high dislocation density...
The results of our research on the application coatings for protecting industrial casting molds are presented. Tests were carried out graphite with deposited Al2O3 containing addition glassy carbon and W/Zr/DLC coatings, both examined after process pouring molten aluminum bronze. applied by two different methods; i.e., plasma spraying in case + coating PVD coating. Reference tests also conducted without use protective seems to be an effective solution. Studies have shown that good resistance...
