Blast furnaces produce a bullion that is high in antimony; this bullion can be readily refined into lead-antimony alloys. Rotary Furnaces In most of the world other than the U.S., rotary furnaces (long, short, and top blown) have replaced blast furnaces as the major smelting vessels for lead recycling.
12%In comparison, the current antimony smelting process, called the "Xikuangshan process," which involves roasting the concentrate in a blast furnace, volatilizing the resulting antimony xide, and reducing the xide with carbon to metallic antimony in reverberatory furnaces, always results in serious environmental pollution and higher ...
This process also keeps the lead from oxidizing. The molten lead flows from the blast furnace into holding pots. Lead may be mixed with alloys, including antimony, tin, arsenic, copper, and nickel. It is then cast into ingots. Smelting of Lead helps in putting recycling process, whereby instead of just throwing away scrap batteries, these scrap ...
Efficient Removal of Arsenic and Antimony During Blast Furnace Smelting of Lead-Containing Materials Dosmukhamedov, Nurlan; Kaplan, Valery; Abstract. The efficient removal of impurities, As and Sb, from recycled lead-containing materials is a key issue in the selection of the appropriate smelting technology for projects involving metal reuse. ...
Blast furnace - Blast furnaces are reduction furnaces that produce hard or antimonial lead containing about 10% antimony. Pretreated scrap metal, rerun slag, scrap iron coke, recycled dross, flue dust, and limestone are used as charge materials to the blast furnace.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

TSL and blast furnace process. The top submerged lance (TSL) and blast furnace operations are the actual smelting part of the process and involve the high temperature reduction of sinter with metallurgical coke to produce a crude lead bullion and slag. Lead bullion contains small amounts of other metals including silver, gold and copper.
The Blast Furnace is a members-only minigame situated in Keldagrim for smelting bars which require coal. The furnace here only requires half as much coal when smelting usually, so it can be useful when smelting the ores that require more coal. The Blast Furnace worlds on Old School RuneScape are Worlds 352, 355, 358, 386 and 387.
tant product of the secondary lead smelter. A blast furnace charge containing used or discarded battery plates, type metal and bear-ing metal is reduced to lead bullion. The bullion is then refined in reverberatory furnaces to meet specifications. Lead–antimony alloys are used in starting-lighting-ignition batteries, ammunition,
Lead Recycling Process Pilot Industries. Apr 15 2019· The lead received from Rotary Furnace smelting is called hard lead crude lead The lead tapped from the furnace has to be cleaned from residual oxides and slag After stirring for a while all the impurities settle at the surface and are skimmed off Lead recovered via blast furnace contains a lot of contamination and undesired components
Xinhua Non-ferrous Metal Smelting Plant is built up with a blast furnace, two bismuth smelting furnaces, a carburizing furnace, a roasting furnace, two silver boiling furnaces, two large-sized reverberatory furnaces and a copper melting furnace as well as a lead electrolyzing workshop and a silver electrolyzing workshop which are mainly based ...
Arsenic and antimony are often present in considerable proportions in the slags from reverberatory furnaces smelting calcined ores. The conditions are different in the blast-furnace when smelting calcined ores, as the gases are of a reducing character. The larger part of the arsenates and antimonates are probably reduced to arsenides and ...

up of the feed to the smelting furnace. 2.2 Secondary smelting The blast furnace was used to provide a low grade antimonial lead, which would be softened—either in a refining kettle or a reverberatory furnace. The high antimony slags would be accumulated for a subsequent blast furnace campaign to produce high antimony bullion
The effect of slag composition on lead losses to slags and on the behavior of associated accessory elements in lead blast furnace smelting has been studied by the Bureau of Mines. Equilibrations of 30 g of lead and synthetic slag doped with cu, in, tl, and sb at 1,200 deg c in co-co2 atmospheres revealed the importance of the feo:sio2 ratio and the basicity ratio, (cao+mgo):sio2, of the slag.
