Oxygen-enriched molten pool antimony refining production process

The invention discloses an oxygen-enriched molten pool antimony refining production process, and belongs to the field of smelting of nonferrous metal. The process comprises the following steps: 1) batching: raw materials are uniformly mixed according to a mass ratio to obtain a mixture; 2) granulation: the uniformly mixed mixture is prepared as spherulites; 3) the prepared spherulites are fed in an oxygen-enriched oxidation furnace for oxidation smelting to prepare a primary high-temperature melt and liquid-state high-antimony ore slag; 4) reduction smelting: the liquid-state high-antimony ore slag flows in an oxygen-enriched reducing furnace for reduction smelting to prepare a secondary high-temperature melt and reducing furnace slag; 5) metal recovery: the reducing furnace slag flows in a fuming furnace through a slag chute; and recovery includes valuable metal; and 6) the smoke is recovered. The process effectively increases the SO2 concentration in smelted smoke to achieve conventional acid preparation sy
