PhD Thesis
Title: Recycling of metals from the stainless steel industry
The production of stainless steel leads to different kinds of residues which are containing significant amounts of metals such as nickel, chromium, molybdenum, vanadium etc. These metal concentrations not only lead to economic losses, but also cause environmental problems when considering the toxicity of chromium(VI) compounds. Therefore, it is necessary to develop a process to recover the valuable elements from the residues and detoxify the resulting slag in order to reuse it in different sectors including the construction industry.
