Abstract

The aim of the study was to determine the detection possibilities for corundum in slags. Corundum may be a harmful component in the secondary utilization of slag. To determine the occurrence and amount of corundum in slag, gravity concentration was used (using the specific weight differences) on tables. The first step of the partial work was detailed characterization of the material using mechanical and physical parameters, including, for example, particle size distribution or friction parameters. In the practical part, the material was first re-sorted. Subsequently, it was examined whether gravity concentration can be used to analyse corundum particles in slags. Individual tests were performed on water and pneumatic plate. Finally, the samples were floated. Some conclusions of the experiments suggest that gravity concentration can be used on plates to capture and analysis corundum minerals in these samples of slags. The quantity of the particles obtained and their size depended on the type of technological treatment. This method has been tested and applied in the laboratory of a company dealing with slag treatment.
