Description
Ferro Silicon is one of ferroalloy which is made from ferrum and silicon. Ferro Silicon uses coke, quartz
(or silica) as raw materials and is made by electric furnace. Thanks to silicon and oxygen are easily compound
into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.
Features
1. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
2. It can be used as a reductant in ferroalloy production and chemical industry.
3. In iron industry it can be used as inoculant and nodulizer.

- Q:Iron is a single element whereas bronze is an alloy of copper and tin. Why would ancient people know how to combine copper and tin while ignoring iron for many centuries? Why did it take so long for the iron age to come along? It makes me mad that the pyramids could have been built of stainless steel, while bronze is only good for making statues.
- A matter of energy and getting the energy required to do certain things. For bronze, a relatively simple fire did the trick. Copper melts at a little over 1000 degress celsius. You can get there with just a few changes to burning wood or charcoal. However, copper, in its pure form is relatively soft. It was relatively easy to add tin to it, and the metal formed (the alloy) is far harder than tin or copper alone. Tin was almost as common as copper, and, like copper, was often mined in a relatively pure state. Iron, on the other hand, tends to be hard (although sometimes brittle, as in cast iron). But it is seldom in a pure state, so one needs the technology to raise the temperature high enough to get rid of the impurities. It took generations to find fires hot enough to do this. And the pyramids are made of STONE, not metal. Working it was just as easy with bronze as it would have been with iron.
- Q:I know that during the process of iron production, Iron ore is always crushed with coke and preheated to give out small lumps with many holes. They are put in the blast furnace afterwards. But why iron ore has to crush with coke before it is fed into the furnace? Why don‘t just put iron ore and coke into the furnace?
- isolate the south pole w/ electron dragging
- Q:5 stars for best answer
- I'm guessing you're trying to power level smithing. Exploring is one of the sure and tested ways. Run around, especially near mountains and look for bandit camps/mines. The reason I say bandit camps is that chests often contain iron ore/ingots there if it's closer to a mountain.
- Q:What's the weight of a cubic iron ore?
- Iron ore is an important raw material for iron and steel production enterprises. Natural ore (iron ore) is gradually selected by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. A mineral aggregate containing iron or iron compounds that can be economically used.
- Q:If metal isnt available then how r Arabs Muslims able to conquer middle east? They had defeated many of the civilizations but how can it be possible without metals? I can only see oil that is represented as there minerals.
- Iron ore is found in deserts. They had a rich supply of metals because they lived in an area with many hydrothermal deposits of copper and other metals. They could trade for anything else they need. Most iron was deposited a billion years ago or longer and the current location of desserts doesn't have much significances that long ago.l
- Q:A:heating the ore and carbon together.B:cooling the ore in an ice bath.C:breaking the ore into small pieces.D:panning.
- A:heating the ore and carbon together. Air blast and charcoal (coke): 2C + O2 2CO. Carbon monoxide (CO) is the principal reduction agent. Stage One: 3Fe2 O3 + CO 2Fe3 O4 + CO2 Stage Two: Fe3 O4 + CO 3Fe O + CO2 Stage Three: FeO + CO Fe + CO2 Limestone fluxing chemistry: CaCO3 CaO + CO2 pedia
- Q:What is the chemical change involved in obtaining iron from iron ore?
- Reduction of the Iron from an oxidation state to a neutral state. Iron Ore reduced to Iron Zero
- Q:What is the souce of most iron supplements? I have heard rumors of some yucky places that iron supplents (pills) may come from.
- Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Therefore, all sources of iron used by human industry exploit iron oxide minerals, the primary form which is used in industry being hematite. However in some situations, more inferior iron ore sources have been used by industrialized societies when access to high-grade hematite ore was not available. This has included utilisation of taconite in the United States, after World War II, and goethite or bog ore used during the American Revolution and the Napoleonic wars. Magnetite is often used because it is magnetic and hence easily liberated from the gangue minerals. Inferior sources of iron ore generally require beneficiation. Due to the high density of hematite relative to silicates, beneficiation usually involves a combination of crushing and milling as well as heavy liquid separation. This is achieved by passing the finely crushed ore over a bath of solution containing bentonite or other agent which increases the density of the solution. When the density of the solution is properly calibrated, the hematite will sink and the silicate mineral fragments will float and can be removed. Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.
- Q:is it because the coke is more reactive than the iron ore and limestone that is also used in the limestone.?
- Yes this is a terrible site
