抜粋

Continuous converting of copper matte using calcium ferrite slag of the CaO-FeOx-Cu2O system is an attractive technology for copper converting. This slag sometimes tends to separate out gypsum under a high oxygen potential required to produce blister copper. Experiments have been carried out to determine the precipitation of CaSO4 in the CaO-FeO x-Cu2O slag with equilibrating with molten copper under the SO 2 partial pressures of 0.2, 0.4, 0.6 and 1.0 atm at temperature range from 1473 to 1573K. The results have revealed that CaSO4 tends to precipitate from slag when the temperature lowers, the CaO content increases, the SO2 pressure increases, or blister copper is oxidized excessively.
