  • Fluorine and chlorine in iron ore by Combustion Ion

    Iron ore is an important resource for steel production. Its natural content of halogens is a quality characteristic due to the corrosiveness of the respective halogenides. Combustion IC applying the sacial vial technology is used for the analysis of fluorine and chlorine in ore. WO 3 usually is added to improve the release of SO2 and therefore sulfur recovery.

    If the ore contains only chalcopyrite the degree of copper solubilization should be minimal. Table 3 shows results from different leach conditions applied to the same ore characterized in Table 1. A suitable condition must be selected in order to minimize copper solubilization on producing a copper concentrate with less than 500 ppm of fluorine.
