Abstract:
Zinc containing residues such as dusts from steel, copper or lead industry have become an interesting secondary raw material because of stricter dumping regulations and high prices of the contained metals. Nevertheless most of the existing recycling routes are pyrometallurgical ones and therefore the melting behavior is of high importance. Simple chemical analysis of the elements does not offer sufficient information due to their complex formation. The paper describes the study of the morphology of such residues which act as a base for detailed investigations with a high temperature melting microscope. The results of these laboratory scale trials give detailed information about the influence of slag components, atmosphere and degree of metallization on the sintering and melting points and with this offer a base for the development or optimization of future recycling processes.
