Does iron ore slag sink to the bottom of the blast furnace?
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
What are the properties of iron filings?
iron
What are the 2 liquids that are tapped off from a blast furnace?

What is the method for purifying iron?
After iron ore is mined it is crushed into a powder then injected into a blast furnace. Under the extreme temperatures the ore melts and since iron is more dense than the impurities, it sinks to the bottom. This leaves a film of "slag" (impurities) on top. The slag is then skimmed off so only the metal remains.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.

Is wrought iron a natural compound?
no, wrought iron is a mixture of cast iron and glassy slag that has been forged and folded repeatedly until the slag forms tiny fibers running the length of the billet. The slag fibers act as reinforcements to counter the brittleness of the cast iron. Until the development of true steels, wrought iron was the strongest and most flexible form of iron.
What is slag a rock?
A slag rock is an artificial rock. Slag is made as a byproduct of industrial processes such as metal mining. It is also produced by iron smelting such as in steel mills.
What is difference between slag and matte?
slag is iron silicate (FeSiO3) while Matte is a crude mixture of molten sulphides.

What is slag powder?
Slag is the unwanted stuff that floats on top of molten metal. It is often glassy. My house has slag powder as insulation in the floors (it was built in 1940 and there was (and still is) an iron foundry in the town.
What is a slag heep?
A slag heap is a pile of waste material that is left over after processing ore to extract metals. It typically consists of non-metallic minerals and by-products formed during the smelting process. Slag heaps are often found near mining or industrial sites.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.
