Potential Toxic Effects of Chromium, Chromite Mining and

During the high temperature smelting of chromite ore, some Cr-III is converted to toxic Cr-VI, contaminating the dust. Prior to smelting, steps employed in some processes, such as milling and agglomeration (i.e. sintering) may also produce Cr-VI. Due to the leaching potential of these contaminants, ferrochrome arc furnace dust is categorized as toxic waste in Canada (waste
