The reduction smelting of antimony oxide from the blast furnace was carried out in the cupellation furnace, and it aimed to reduce the gold content in antimony oxide. Refined antimony was obtained by reducing, smelting, and refining the antimony oxide from cupellation furnace to remove arsenic and lead.
The reduction smelting technology most commonly utilizes the antimony oxide powder reduction in a reverberatory furnace. Here, antimony oxide powder, reduced coal, and …
To recover antimony from the slag, it was necessary to carry out a reducing fusion with slag using pyrometallurgical methods with ternary diagrams; FeO: Na 2 O: SiO 2 and FeO: SiO 2: …
This process relies on the volatility characteristics of antimony xide. In the process, high-grade stibnite is concentrated by blast furnace volatilization smelting to obtain high purity antimony xide, then the collected antimony oxide powder is placed in a reverberatory furnace for the reduction smelting preparation of antimony metal.
The facility consists of 3 reduction furnaces, 6 fuming furnaces and 1 antimonate drier. ... Six propane-fired fuming furnaces are used to oxidize antimony metal (containing 99.8% antimony) to antimony xide. Each furnace is equipped with a baghouse, which collects the antimony xide. There is also one furnace, which is used to reduce

Blast furnace volatilization—reduction smelting is currently the most commonly used method for treatment of concentrates; capable of smelting a wide range of antimony …
U.S. Antimony Collected from drums of "Reduction furnace slag" that were designated as containing less than 5 percent antimony. AC-1-AO-06 U.S. Antimony Collected from drums of "Reduction furnace slag" that were designated as containing 5 to 10 percent antimony. LI-1-AO-01 Laurel Industries Collected from drums used to collect the material.
The invention discloses an antimony oxide reduction smelting device, which comprises: the furnace body and inductor, gas phase district, slag layer district and metal layer district are injectd from top to bottom in the furnace body, the gas phase district is equipped with antimony oxide material entry, exhaust port and burning nozzle, slag layer district is equipped with the slag …
Selective determination of arsenic (III, V), antimony (III, V), selenium (IV, VI) and tellurium (IV, VI) by extraction and graphite furnace atomic absorption spectrometry ... separation of the organic phase, (iii) reduction of the four elements in aqueous solution in the higher oxidation state with titanium (III) chloride, (iv) second ...
The powdery crude antimony xide is reduced by a carbonaceous reductant in a reverberatory furnace at 1,000–1,200 °C to produce crude antimony. Crude antimony can be …
This is mostly the volatilization smelting (roasting) – reduction smelting. Antimony sulfide is susceptible to volatilization and oxidation, so it can be used to produce crude antimony xide at a temperature above 1,200 °C. ... A small volume of antimony matte is also generated and flows together with antimony metal via the furnace base ...
The Kaldo furnace smelting slag is produced in the process of recovering gold and silver by treating copper anode slime by adopting a Kaldo furnace main process in a precious metal smelting plant, mainly comprises elements such as lead, antimony, bismuth, tin and the like, also contains 4-5 kg/t of silver and 50-60 g/t of gold, and has extremely high value.
In figure 2, the reduction reactions of PbO, Sb 2 O 4, and Sb 2 O 5 with CO (g) and CO 2(g) are shown, where it is observed that the reduction ... a stable non-volatile solid phase that will remain in the antimony volatilization furnace. Citation: Christian Álvaro Mendoza Ramos. "Recovery of Antimony from Refinery Slag of Unified Mining ...
Antimony is considered an important metal, and various antimony compounds are widely used in electronics, flame retardants, chemicals, alloys, and semiconductor materials. 1 Antimony exists mainly in the form of antimony sulfide, which is usually smelted by volatilization in the blast furnace. However, the process has some problems, such as a complex process …
Cleaning of high antimony smelting slag from an oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. The effects of added CaO, mass ratio of coal (experimental) to coal (theoretical) (ω) and the slag type on the reduction procedure were considered. The contents of Sb and Au were investigated. Iron contamination …
Antimony is typically classified as a volatile heavy metal, and low-grade ores are commonly produced by pyrometallurgical methods . …
Industrially, reduction of antimony oxide to metallic antimony is achieved by heating and the addition of carbon in a reverberatory furnace. Volatilization of antimony can be reduced by the addition of an alkaline flux but it cannot be eliminated [ 20 ] and volatilized antimony oxide is recovered in flues, condensing pipes, bag houses ...
