Untersuchung des Einflusses von einzelnen Parametern auf die Zinnausbringung im Konverterstaub

The increasing amount of scrap and growing demand of numerous metals require improvements in the typical recycling processes to meet customer specifications for quanitity and quality. Copper recycling produces for example oxidic byproducts in addition to the Cu-melt, which can later be recovered and reduced into their metallic form. The following thesis describes the influence of various parameters during the converter process, such as the addition of reducing agents and other components like slag-formers. The main goal of the research was to increase the tin output in the off-gas during the converter process without decreasing the quality of the copper melt. As part of this thesis it was necessary to carry out experiments at the production facilities. The obtained results had to be analyzed and compared to different scientific papers, so it was possible to achieve some improvements for the typical converter process.
