Embodiment 1

[0073] Such as figure 1 As shown, this process is used for antimony smelting production process, and the antimony smelting production process is divided into two stages: electrothermal volatilization and electrothermal reduction. Both stages use the heating method of electrode arcing to smelt antimony-containing materials.

[0074] In the electrothermal volatilization stage, 100kg of dry mineral material and 4kg of coke are first added, and the above raw materials are heated by electrode arc discharge to form a bottom molten pool. Keep the electrode 10cm away from the bottom of the furnace, and start feeding at a constant speed after the current is stable and the furnace temperature is 1200°C. After the electrode is energized, adjust the input power according to the temperature in the furnace to maintain a stable input power, adjust the voltage to 100V, and maintain the current value at 1KA by adjusting the insertion depth to ensure that the furnace temperature rises to 1400°C...

Embodiment 2

[0079] Such as figure 1 As shown, this process is used for antimony smelting production process, and the antimony smelting production process is divided into two stages: electrothermal volatilization and electrothermal reduction. Both stages use the heating method of electrode arcing to smelt antimony-containing materials.

[0080] In the stage of electric heating, 100kg of dry mineral material and 4kg of coke are first added, and the above raw materials are heated by electrode arc discharge to form a bottom molten pool. Keep the electrode 8cm away from the bottom of the furnace, and start feeding at a constant speed after the current is stable and the furnace temperature is 1100°C. After the electrode is energized, the input power is adjusted according to the temperature in the furnace, the voltage is adjusted to 80V, the current value is maintained at 1KA by adjusting the insertion depth, the input power is guaranteed to be 80KW, and the furnace temperature is raised to 1400...

Embodiment 3

[0085] Such as figure 1 As shown, the antimony smelting production process is carried out by using this process, and the antimony smelting production process is divided into two stages: electrothermal volatilization and electrothermal reduction, and the same electrode heating method is used in both stages.

[0086] In the stage of electric heating, 100kg of dry mineral material and 4kg of coke are first added, and the above raw materials are heated by electrode arc discharge to form a bottom molten pool. Keep the electrode 100mm away from the bottom of the furnace, and start feeding at a constant speed after the current is stable and the furnace temperature is 1200°C. After the electrode is energized, the input power is adjusted according to the temperature in the furnace, the voltage is adjusted to 100V, the current value is maintained at 1KA by adjusting the insertion depth, and the input power is 100KW to ensure that the furnace temperature rises to 1400°C within half an ho...

Abstract

The invention relates to an extraction system and extraction method of antimony metal. The extraction system comprises a volatilization unit, a dust collection device and a reduction unit which communicate with each other in a sequential mode. The reduction unit is an electrode heating reduction unit, and comprises a reduction device, a first electrode lifting device and a first pressure supply device, wherein the reduction device is provided with a first smelting pool. The reducing device is further provided with an antimony-containing dust inlet and a reducing agent inlet, the antimony-containing dust inlet and the reducing agent inlet communicate with the first smelting pool, and the antimony-containing dust inlet communicates with the dust collection device. At least two first electrodes are arranged on the first electrode lifting device, and the first electrode lifting device is used for adjusting the depth of the first electrodes in the first smelting pool. A first voltage supplydevice is used for providing voltage to the first electrodes. According to the extraction system of the antimony metal, equipment and operation process can be simplified, so that the investment costcan be greatly reduced, and the use of fossil fuels as well as the energy consumption can be reduced; in addition, the concentration of SO2 in the tail gas is high, thus being suitable for the recycling of acid so as to solve the environment pollution problem caused by antimony smelting.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an extraction system and an extraction method of antimony metal. Background technique [0002] More than 95% of the antimony smelters in my country use the fire antimony smelting process to process the antimony sulfide concentrate. 2 o 3 , then to Sb 2 o 3 Carry out reduction smelting and refining to produce metal antimony. Among them, the volatilization efficiency of antimony sulfide concentrate is the most important link that directly affects the technical and economic indicators of antimony smelting. The existing antimony metal smelting processes are mainly divided into the following types: [0003] (1) Blast furnace volatilization smelting-reverberatory furnace reduction smelting process [0004] Blast furnace volatilization smelting-reverberatory furnace reduction smelting and refining is the main process of antimony smelting in my country at present. This process mainly...
