lead smelting - wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production [clarification needed] begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing

Jan 12, 2020 · The iron is poured into the stacks along with coke (carbon-rich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. The sintering process forms pieces of ore that are 10-25mm, and these pieces are then mixed with coke and limestone

This reacts with the iron ore (iron oxide) to produce carbon dioxide (CO2) and molten iron – which settles to the base of the furnace and is tapped at regular intervals. Hot gases rising inside the BF preheat incoming material, initiate ore reduction and convert limestone into CO2 and calcium oxide

Agglomeration of Iron Ore: Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the fee. So, they are agglomerated (by igniting at lower temperature causing only interfacial fusion) into larger lumpy pieces with/without addition of additives like limestone, dolomite etc

the integrated steelmaking process featuring the blast furnace/basic oxygen furnace (BF/BOF), where iron ore is the major source of iron units; and; electric steelmaking based on the electric arc furnace (EAF), where steel scrap or direct reduced iron (DRI) are the major iron feedstock materials. Figure 1: major steelmaking process routes

The limestone combines with impurities and molten rock from the iron ore and sinter, forming a liquid ‘slag' which, being lighter than the metal, floats on top of it. The blast furnace The charging system at the top of the furnace also acts as a valve mechanism to prevent the escape of gas, which is taken off through large-bore pipes to a gas

Jul 07, 2017 · Addition of limestone through sinter is more preferred route since CO2 of limestone is driven out during the sintering process. In case of sintering, limestone is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix. In case of direct feed to blast furnace, limestone lumps of 10 mm to 40 mm size are used. In case of limestone addition through sintering, these days calcined limestone …

Apr 02, 2010 · Original purpose of the iron-ore sintering process is to agglomerate fine ores into lump burdens for blast furnace (BF). Since sintering conditions, e.g., kinds of ores and used fluxing materials, and pregranulation processes, strongly affect the metallurgical properties of the produced sinter, many researches and developments on the sintering process have been made in order to achieve a stable …

SLRM is operating a 262 m 3 (working volume) Blast furnace since 2012. Sinter , calibrated lump ore, limestone, dolomite, quartzite and coke are charged into the MBF from top and hot air is passed from the bottom. Ascending oxygen in the air reacts with the carbon in the coke to form CO which reduces the descending iron oxide to iron
