[0080] The coke is fed into the precipitation tank 130 through the reducing agent feeding port to form the reducing agent filtering layer 131. Mix limestone and powdered brittle sulfite with a particle size of no more than 100 microns in a ratio of 1:20 (weight ratio), and then use an oxygen-rich gas with an oxygen content of 40v% to mix limestone and powdered brittle sulfite Spray into the reaction tower 10, and smelt the powdered brittle antimony lead ore at 1100 degrees Celsius to obtain antimony-lead alloy and antimony-rich lead slag. Among them, the water content of limestone and powdered brittle antimony lead ore is not more than 0.3wt%.

[0084] The powdered brittle antimonite used in this example is the same as the powdered brittle antimonite used in Example 1.

[0085] The coke is fed into the precipitation tank 130 through the reducing agent feeding port to form the reducing agent filtering layer 131. Mix pulverized coal, quartz sand and powdered brittle antimony lead ore with a particle size not greater than 80 microns (the weight ratio of quartz sand and powdered brittle antimony lead ore is 1:5), and then use the oxygen content of 99.6v% The oxygen-enriched gas will spray the mixture of powdered coal, quartz sand and powdered brittle antimony lead ore into the reaction tower 10, and smelt the powdered brittle antimony lead ore at 1500 degrees Celsius to obtain antimony lead alloy and Antimony-rich lead slag. Among them, the water content of pulverized coal, quartz sand and powdered brittle antimony lead ore is not more than 1wt%.

[0089] The powdered brittle antimonite used in this example is the same as the powdered brittle antimonite used in Example 1.

[0090] The coke is fed into the precipitation tank 130 through the reducing agent feeding port to form the reducing agent filtering layer 131. Mix soot, pulverized coal, flux and powdered brittle antimony with a particle size of not more than 60 microns (flux includes limestone and quartz sand and the weight ratio of flux to powdered brittle antimony is 1:2), and then use Oxygen (i.e. pure oxygen) sprays the mixture of soot, pulverized coal, flux and powdered brittle antimony lead ore into the reaction tower 10, and smelts the powdered brittle antimony lead ore at 1300 degrees Celsius to obtain antimony Lead alloy and antimony-rich lead slag. Among them, the water content of pulverized coal, flux and powdered brittle antimony lead ore is not more than 0.5wt%.

Abstract

The invention discloses a device and a method for smelting antimony. The smelting device comprises a reaction tower and a nozzle, wherein a settling pond is arranged on the lower part of the reaction tower; a separator is arranged in the settling pond and used for separating a furnace chamber of the settling pond into an oxidation zone and a reduction zone which are communicated; the top of the reaction tower is provided with a reducing agent charging hole; the top wall of the oxidation zone is provided with an oxidation zone smoke outlet; one of the side wall and the top wall of the reduction zone is provided with a reducing agent access port; the top wall of the reduction zone is provided with a reduction zone smoke outlet; and the nozzle is arranged on the top of the reaction tower for injecting one of the fluxing agent, powdered jamesonite, enriched oxygen and oxygen in the reaction tower. The smelting device of the antimony has the advantages of high yield and production efficiency, low power consumption and energy consumption, high safety and environment protection, and the like.

Description

Technical field [0001] The invention relates to the field of metal smelting, in particular to an antimony smelting device and an antimony smelting method. Background technique [0002] At present, brittle sulfur antimony lead ore has been smelted by boiling roasting-reduction smelting-blowing-refining process. That is, the brittle sulfur antimony lead concentrate is roasted and desulfurized in a fluidizing furnace, calcine ingredients are sintered, and reduced and smelted in a blast furnace to produce antimony-lead alloy. The antimony-lead alloy is then smelted in a reverberatory furnace to obtain antimony oxide powder and bottom lead, and the antimony oxide powder is passed through the reverberatory furnace Refining and producing refined antimony, the bottom lead is electrolyzed with lead silicofluoride to produce electric lead. The existing brittle sulphur antimony lead ore smelting process has the disadvantages of complicated process and high energy consumption. Summary of t...
