ABSTRACT
The tanning industry, during the leather tanning, produces shavings that, because of the method used, have chromium in its chemical composition. Volume reduction and energy utilization can be achieved by shavings incineration. The aim of this work is to show that the recycling of the metal contained in leather shaving ashes is possible as raw material for stainless steel production, relieving the environment of a dangerous residue. The elaboration of a ferroalloy with similar characteristics of the commercial HC-FeCr ferroalloy was investigated at the laboratory scale. Prior, a thermodynamic analysis was carried out, simulating the process of chromium oxide reduction in order to provide the basis and the most favorable conditions for the experiments. At the laboratory level, it was demonstrated that is viable the reutilization of chromium bearing ashes from the incineration of leather shavings for the production of HC-FeCr.
