Why is limestone add to blast furnace?
To remove impurities, mainly sand ( silicon dioxide). It is sometimes reflerred to as a 'flux'. The limestone undergoes thermal decomposition. CaCO3 = CaO + CO2 The CO2 reacts with the coke to produce carbon monoxide CO2 + C = 2CO The Carbon monoxide reduces the iron ore ( iron oxide) to iron Fe2O3 + 3CO = 2Fe + 3CO2 The iron is tapped off at base of the furnace. The CO2 recircluates to form more carbon monoixide. The Iron ore contains a number of impurities , notably sand (silicon dioxde ; SiO2) These impurities react with calcium oxide (CaO) produces from the thermal decomposition of ;omestone, to form 'slag'. CaO + SiO2 = CaSiO3 (calcium silicate (Slag)). Since tons of slag is produced it is used to make 'breeze blocks' for building and road surfaces.
How is slag removed from the furnace?
Gas BlowersGas blowers use blasts of a gaseous material to remove slag from furnace walls. These tools work in a way that is similar to other blowing tools, like snow blowers or leaf blowers, but use strong, concentrated bursts of gas. Blowers for slag removal, which include jetblowers and sootblowers, often use heated air. This weakens the connection between the slag and furnace wall and leads to quick removal. Gas blowers usually use air or steam. Steam, given its high temperatures and moisture content, attacks slag in a different and more aggressive way than dry air. Sootblowers exist primarily to remove soot from furnaces, though many factories with coal furnaces use them as slag-removal tools in tandem with other tools such as water cleaners and chemical treatments.
What to add to remove Pb from copper in anode furnace?
Add silica in anode furnace it will make lead silicate and skim out with anode slag
What is difference between slag and matte?
slag is iron silicate (FeSiO3) while Matte is a crude mixture of molten sulphides.
Why slag is produced in metal extraction?
Metals are extracted from their ores which contain several impurities, the lighter impurities are removed by slag formation.
How do you remove slag after smelting metal?
slag of induction furnace having 49% of feo . is it higher side

What is added to remove rocky waste and it forms molten slag?
Limestone
What are mercuryvenusearthmars made of?
Mostly iron on the inside, and silicon oxide (rocks) {or you could say "slag"} on the outside. Everything else is just trace stuff.
What is difference between gangue and slag?
Gangue is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed or simply rocky impurities.While slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.
How do you prevent the occurrence of slag inclusion and undercut?
The following techniques can be used to prevent slag inclusions: Use welding techniques to produce smooth weld beads and adequate inter-run fusion to avoid forming pockets to trap the slag. Use the correct current and travel speed to avoid undercutting the sidewall which will make the slag difficult to remove.
Is coke used to oxidise slag?
Coke is not used to oxidize the slag . It is carbon that is used to oxidize slag.
What is slag called in Australia?
its still called slag
What is the formulae for slag?
Slags are basically artificial silicates of varying formula. The is no overall formula for slag because it is dependent on the ingredients used and just what is being smelted. For example slag from iron smelting is different than from copper smelting. The most important aspects of slags are that they contain all the unwanted materials while allowing an economic separation of the valuable constituents of the ore. The chemistry of a given slag depends on the waste components of the ore plus the fluxes used to slag them off.

What is welder slag?
Welder slag is a byproduct resulting from the welding process, often forming a layer on top of the welded joint. It consists of the residue from the flux used in the welding rod or wire, which helps protect the weld pool from impurities and contaminants while it cools. Slag is typically removed after welding to inspect the quality of the weld and ensure proper fusion.
What is slag hammer?
It is a hammer with a flat broad head for knocking slag off.
