Abstract

The methods of waste processing and salvaging are considered for steelmaking slags. The dump slags of the Zlatoust metallurgical works are analyzed. A scheme of two-stage metal reduction from the dump slags using the reduction– melting scheme is developed and tested under laboratory conditions. The reduction parameters that correspond to the maximum recovery of a metallic component from the slags are found. Experimental researches included experiments on solid-phase and liquid-phase recovery of slag samples at temperatures of 1000-1500°C. The results of thermodynamic modeling and experimental high-temperature slag processing allow speaking about the advisability of preliminary solid-phase recovery slag in the atmosphere of carbon monoxide with subsequent high-temperature (liquid phase) recovery to obtain the separate metal fractions.
