Continuous process for refining sulfide ores

Claim 1

A SYSTEM FOR CONTINUOUS PROCESSING OF METAL SULFIDE ORES TO PRODUCE CRUDE METAL THEREFROM, WHICH CONSISTS OF: A. A SMELTING FURNADE 1 FOR SMELTING THE RAW MATERIAL METAL SULFIDE ORES, WHICH IS PROVIDED WITH A LANCE 6, A BURNER 7, A MELT DISCHARGING PORT 8, A SEALING DAMPER 9 FITTED ON THE OUTSIDE OF THE MELT DISCHARGING PORT 8 IN A MANNER TO BE SUFFICIENTLY WIDE TO CLOSE THE DISCHARGING PORT AND MOVABLE UP AND DOWN TO CONTROL A SLAG LAYER IN THE FURNACE AT A REQUIRED CONSTANT THICKNESS, A MELT OVERFLOW WEIR 10, AND A REVERT SLAG CHARGING PORT 22A, B. A SEPARATOR 2 FOR SEPARATING MATTE AND SLAG IN THE MELTS TRANSFERRED FROM THE SMELTING FURNACE, WHICH IS PROVIDED WITH HEATING MEANS 13 TO MAINTAIN THE SAME AT A REQUIRED TEMPERATURE, A MELT CHARGING PORT 14 BEING COMMUNICATED WITH THE MELT OVERFLOW WEIR 10 TO THE SMELTING FURNACE, A SLAG DISCHARGING PORT 15, A MATTE TAPPING PORT 16, A MATTE SIPHON 17, AND A MATTE OVERFLOW WEIR 17A, AND C. A BLISTER FURNACE 3 FOR MAKING WHITE METAL, CRUDE METAL AND BLISTER FURNACE SLAG FROM THE MATTE TRANSFERRED FROM THE SEPARATOR, WHICH IS PROVIDED WITH A LANCE 26, A MATTE CHARGING PORT 18, A BLISTER FURNACE SLAG DISCHARGING PORT 22, A CRUDE METAL TAPPING PORT 23, A CRUDE METAL SIPHON 24, AND A CRUDE METAL OVERFLOW WEIR 25, SAID SMELTING FURNACE, SEPARATOR, AND BLISTER FURNACE BEING ARRANGED IN SUCH A MANNER THAT THE REACTION CONDITIONS SUCH AS TEMPERATURE, COMPOSITION, SURFACE LEVEL, AND INTERFACIAL LEVEL OF A MELT RESIDING IN EACH FURNACE MAY BE CONTROLLED INDEPENDENTLY OF THE OTHER, THE FEEDING QUANTITY OF THE MELT INTO THE SEPARATOR BEING EQUILIBRATED WITH THE RATE OF FEEDING OF THE RAW MATERIAL INTO THE SMELTING FURNACE BY MAINTAINING THE MELT OVERFLOW WEIR 10 AND THE BOTTOM END OF THE SEALING DAMPER AT THEIR RESPECTIVE REQUIRED CONSTANT LEVELS TO SET THE RESIDENCE QUANTITIES OF THE MATTE AND SLAG IN THE SMELTING FURNACE, AND THE FEEDING QUANTITY OF THE MATTE INTO THE BLISTER FURNACE BEING EQUILIBRIATED WITH THE FEEDING RATE OF THE MELT INTO THE SEPARATOR BY MAINTAINING THE SLAG CHARGING PORT 15 AND THE MATTE OVERFLOW WEIR 17A AT THEIR RESPECTIVE CONSTANT LEVELS TO SET THE RESIDENCE QUANTITIES OF THE MATTE AND SLAG IN THE SEPARATOR.
