Embodiment 1

[0050] This embodiment is an example of the device used in the processing method of the brittle pyrosterite of the present invention.

[0051] With reference to Fig. 1, the device used in the processing method of the brittle sulfur-lead-antimony ore of the present invention is mainly composed of fluidized fluidized furnace 1, "U" shape flue 2, upper calcined sand storage bin 3, lower calcined sand storage bin 4, and screw feeding Machine 5, electric furnace 6, horizontal flue 7, constant temperature condensing drum 8, continuous fuming furnace 9, fuming furnace horizontal flue 10, flue gas leaching tower 11, leaching soot settlement tank 12, siphon slag discharge port 13 , siphon lead discharge port 14, furnace cleaning port 15, overflow partition 16, siphon partition 17, blower port 18, sulfur product receiving bucket 19, arsenic product receiving bucket 20, antimony product receiving bucket 21, multi-stage The countercurrent melting tank 22, the melting tank 23, the electric...

Embodiment 2

[0061] This embodiment is the processing method steps and process conditions of the brittle pyrostibite described in the present invention.

[0062] The main components of brittle pyrostibite: Pb27.20, Sb18.98, Zn5.59, S23.00, Fe13.92, As1.22, Sn1.07, Cu0.2~0.4, In0.034, Cd0.055 , Bi0.16, Ag0.125, C1.84, CaO0.65, SiO 2 2.60, Al 2 o 3 0.27. The purpose of the fluidized furnace roasting in this embodiment is to desulfurize the brittle pyridoxite, and does not require the removal of arsenic and antimony. Antimony is required to generate antimony tetroxide (Sb 2 o 4 ), the controlled roasting conditions are: boiling layer temperature 700-750°C, excess air coefficient 1.2-1.35 by air blast, desulfurization rate 95%.

[0063] The flue gas from the fluidized fluidized furnace enters the upper calcine storage bin 3 through the "U"-shaped descending flue, and then rises to the bottom line of the flue gas outlet along the "U"-shaped ascending flue through the leaching of the calci...

Embodiment 3

[0068] This embodiment is an application example of using the flue reduction tank of the present invention. As a solution to SO 2 and a small amount of As 2 o 3 Environmental pollution problems, while recovering a small amount of volatilized PbO and a small amount of Sb that did not enter the calcine 2 o 3 , using flue reduction tank to reduce SO 2 reduced to elemental sulfur, the As 2 o 3 reduced to metallic arsenic or realgar (A 2 S 2 ), reducing lead antimony oxide to metallic lead and metallic antimony.

[0069] Referring to Figure 6, the flue reduction tank is composed of a flue gas pipeline 2701, a sealed feed system 2702, a first reduction tank 2703, a porcelain ring 2704, a sieve plate 2705, a reduction residue sealed conveying screw 2706, and a sealed slag discharge barrel 2707 , Reduction liquid lead receiving tank 2708, high temperature condensation drum 2709, condensed liquid lead receiving tank 2710, metal antimony sealed discharge tank 2711, second secti...

Abstract

The present invention is jamesonite treating process and apparatus. The process includes roasting, smelting and fuming. The apparatus has one U-shaped flue connected to collect dust and preserve heat; one spiral feeder with the functions of feeding material stably, mixing materials and dewatering flux and coke; one electric furnace, one multistage continuous fuming furnace and one multistage countercurrent smelting and separating trough connected for continuous operation with high In, Ag, Pb, Zn and Sb recovering rate and low power consumption; one constant temperature condensing rotary drum for collecting In-containing Pb and Zn liquid and solid Sb and separating out As, S and other volatile impurity; and one flue reducing tank to avoid environmental pollution caused by SO2 and As2O3.

Description

1. Technical field [0001] The invention relates to a method and device for smelting non-ferrous metals, in particular to a method and device for treating brittle pyrotite. 2. Background technology [0002] The smelting method of brittle sulfur-lead-antimony ore is currently only produced by smelting lead-antimony alloys. The production process of this kind of alloy is very complicated. After repeated oxidation blowing and reduction smelting, the final product is lead and high-lead-antimony, and the recovery rate is also low. The recovery rate of the main metal is 83-85% for lead and 75-78% for antimony. %, silver was recovered in lead electrolysis, and other useful elements were not recovered. This not only causes a waste of resources, but also pollutes the environment. Therefore, a relatively simple smelting process must be sought to deal with this complex lead-antimony composite ore and obtain its due value. 3. Contents of the invention [0003] The purpose of the pre...
