The invention provides an oxygen-enriched bottom-blowing double-port sulfonium-discharging inclined smelting furnace, relating to the field of colored metallurgy. The smelting furnace comprises a furnace body, a feed inlet, a low-position sulfonium-discharging port, a sulfonium-discharging port, a slag outlet, a smoke channel, oxygen guns, oxygen-enriched air, copper sulfonium, slag liquid and mineral aggregates. The smelting furnace is characterized in that the furnace body is longitudinally inclined by a small angle, the oxygen guns are in staggered and crossed arrangement in two rows, the distances among the oxygen guns are gradually reduced from the start end to the final end, and the low-position sulfonium-discharging port, the sulfonium-discharging port and the slag outlet are all arranged on the end surface of the final end of the furnace body. Compared with the prior art, the smelting furnace has the advantages of reasonable design, simple structure, uniform mixing of the oxygen-enriched air and the copper sulfonium, rapid and violent reaction, high free degree of various ions, long settling and separating time, large space, low energy consumption, wide application range of the mineral aggregates, high multi-metal capturing rate, smelting cost reduction, smelting efficiency improvement, and the like, thereby having good generalization and using values.
