Method and device for smelting jamesonite by bottom-blowing pool

The invention relates to a method and a device for smelting jamesonite by a bottom-blowing pool. The method comprises the following steps of: performing pool smelting, oxidation and desulfurization on the jamesonite by using a bottom-blowing oxidation furnace to produce antimony-containing high-lead slag, a lead-antimony alloy and flue gases suitable for acid preparation; reducing the antimony-containing high-lead slag and blowing the lead-antimony alloy by using a bottom-blowing smelting furnace to produce antimony oxides and lead bullion capable of being used for electrolysis; and reducing the antimony oxides by using a bottom-blowing reduction furnace to produce needle antimony. In the smelting method of the invention, the three bottom-blowing furnaces and an electrically-heated settler are adopted to treat the jamesonite to produce the lead bullion, the needle antimony and the slag; therefore, compared with the prior art, the method has the advantages of short flow, good lead-antimony separation effect, fewer intermediate products, less revert, high resource utilization rate and production continuity; and the bottom-blowing oxidation furnace can realize spontaneous heating balance by sulfide combustion with low energy consumption and high recovery rate and can greatly reduce the cost.
