| Abstract: |
| The chemical composition of slag from oxygen enrichment side-blowing bath smelting process (OESBBSP) was confirmed according to the slag composition of Ausmelt furnace, Isaac furnace and Mitsubishi furnace. The problems which occurred during OESBBSP practice included high monomer sulfur content in waste gas, large vibration in furnace body and waste heat boiler, serious accretion in ascent stage and radiation area of waste heat boiler, condensation acid emerged in waste gas, lessening copper recovery due to a larger amount of smoke dust. With the effort of two years’ improvement, the daily processing amount of copper concentrate, blister copper output, power and coal consumption, comprehensive energy consumption and production cost all met the design requirements. |
