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:is iron hard or easy to get?: If you want to try something cool, get some cereal, like corn flakes, and mash it up in some water and get a magnet and you can collect some iron fillings from the cereal.

Q:And also, what are the percentages?thanks: merely off the surprising of my head i can provide help to comprehend China and Japan are on there, perhaps Korea and the states. merely pass on the CIA factbook authentic rapid in a sparkling tab and you gets your awnsers.

Q:I‘ve just started second year majoring in Geology, and I‘m thinking about Vac work and my eventual career.Ideally, I would like to work as a Mine Geologist, but I don‘t know the difference between working with iron ore, copper, nickel and gold.Choosing where I do my Vac work is important, as a lot of Graduate opportunities lead on from there, so I would like to be prepared and ultimately choose Vac work with a company that I could see myself working for.So to the geologists out there, what is the best route to go down - iron? Copper? Gold? If I start with one, does it lend itself to another? Is one commodity more stable (less cyclical) than another? What is the main differences in working with the different types of ores as a mine geologist?Thanks!!: Jenny, You failed to point out how your grades have been for the period of university. The merciless reality is that plays a very fundamental position in who gets job offers and who would not even when there is demand for school graduates. With the downturn in the financial system throughout 2009 most of us were just completely happy to hold on to our jobs and plenty of corporations backed off of institution recruiting altogether. As a minimum one oil gas producing enterprise reneged on job offers to school grads which was once horrible. Oil gasoline recreation has picked up in the course of 2010 overall and also job opportunities. Nonetheless, i am no longer as acquainted with Petroleum Geology demand as i am for Engineering and plenty of firms are nonetheless limiting the number of latest hires they're allowed. I can state that there's still a massive scarcity of both Petroleum Engineers and Earth Scientists within this industry and that gap will continue to grow as most of us retire within the subsequent 5 - 10 years. I work for a essential US producing organization. If you are interested contact me and i'd be glad to move your resume to my enterprise's more than a few Earth Science departments. No promises but it's a lot better than trying to work through Human assets.

Q:Coal based DRI: see what temperatures physical properties change at for melting and then look at the phase diagram (temperature vs %weight)

Q:Thanks: Typical process: (1) Blast the ore and remove it from the ground. (2) Grind it to powder in huge mills (or mix with water and grind to mud in a wet process) (3) Separate it from contaminants using magnetic separation (for magnetite) or a process called froth flotation (for hematite). (4) Settle it and decant off most of the water. Filter off the rest of the water. (5) Pelletize the concentrate on pelletizing disks or in pelletizing drums to make grape-sized balls. (6) Roast the pellets to harden them and dry away residual water. (7) Transport to a smelter where one typically uses a blast furnace or arc furnace. Carbon (coke) is added along with a silica flux. The coke combines with the oxygen in the ore leaving metallic iron, and other impurities combine with the silica to form slag.

Q:When producing steel, carbon monoxide is expelled - where does it come from?- Liquid Oxygen combines with Coke (O+C CO)- Oxygen from Iron ore combines with Coke (FeO+C FeC+CO)- Incomplete combustion of Coke (C+O CO)- Carbon Dioxide breaks down (CO2 CO+O)thanks a lot: *The production of iron requires three important raw materials: iron ore, coal converted to coke, and limestone. Following are the stages where the CO can be evolved during iron making process: **The coal is converted to a product called coke in coking ovens. The three raw materials are added to the top of the blast furnace. A blast of air containing oxygen is forced in from the bottom of the furnace. This causes the coke to burn with an intense heat of almost 2000 C. The reaction is carbon plus oxygen to produce carbon monoxide (incomplete combustion due to lack of air). 2C + O2 CO **The main reaction is then between the iron oxide, Fe2O3, with the carbon monoxide to produce molten iron metal and carbon dioxide. An alternate reaction is with the coke, C, to produce iron and more carbon monoxide. The molten iron collects on the bottom of the furnace and when cooled is called pig iron with many impurities. Fe2O3+3C2Fe+3CO **Much of the carbon dioxide is reduced with more carbon from the coke to make more carbon monoxide. ** 1.At the high temperature at the bottom of the furnace, carbon dioxide reacts with carbon to produce carbon monoxide. C +CO22CO 2.In the hotter parts of the furnace, the carbon itself also acts as a reducing agent. Notice that at these temperatures, the other product of the reaction is carbon monoxide, not carbon dioxide. *Pl. go through following link: www.chemguide .uk/inorganic/ext.

Q:A sample of iron ore consists only of haematite(Fe2O3) and contains 65% iron, what is the percentage of haematite in the ore?Answer : 92.9%Thanks for any responses.: If there was only Haematite in the ore there would be 69.94% iron (mFe2 / mHaematite). Provided there is only 65% of iron in the sample, so there must be some non-iron compounds in the ore. To find out how many % the Hematite is you take the 65% / 69.94% 92.9%
