Summary

The pyrometallurgical process is a solution to the problem of recycling chromium bearing refractories from the glass manufacturing industry. This process eliminates the need for stabilization and land disposal by reclaiming these metals for further use. In this paper, the steps of pyrometallurgical process (feed preparation, reduction, smelting, and casting) are examined in detail. The recovery of the metal and nonmetal components of the wastes is explained.
