Description
Metal Silicon is a kind of ferroalloy which is composed of metal and silicon.Ferro silicon is one of metal products. Ferro Silicon uses coke, quartz
(or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound
into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking. It is playing more and more important role in the industry.
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. Ferro silicon 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:How many grams of pure H2SO4 can be obtained from 250 grams of iron ore if the ore is 82% FeS2? The reactions involved are given below:4FeS2 + 11 O2 --gt; 2 Fe2O3 + 8 SO2 (95% efficient)2SO2 + O2 --gt; 2SO3 (90% efficient)SO3 + H2O --gt; H2SO4 (90% efficient)
- Calculate first the mass of pure FeS2 from iron ore that will react with O2. The rest is just an inert material and will not react with O2. mass of pure FeS2 in iron ore 250 g 0f iron ore x (82/100) mass of pure FeS2 in iron ore 205 g By stoichiometric analysis: calculate the mass of SO2 produced in the first reaction since this SO2 is what we need to react with O2 in the second reaction. mass of SO2 ( mass of pure FeS2 / MW of FeS2 ) x (stoichiometric ratio of SO2 with FeS2 from the first chemical equation x MW of SO2 mass of SO2 (205 g / 119.98) x (8/4) x 64 218.70 g Take note that the mass of SO2 218.70 g is obtained at 100% efficiency. It was stated in the problem that the reaction goes 95% completion/efficiency, therefore calculate for the mass of SO2 at 95 % efficiency: mass of SO2 (95% efficiency) 218.70 x (95/100) 207.77 g Again, by stoichiometric analysis: calculate for the mass of SO3 produced from the second reaction using the mass of SO2 (95% efficiency): mass of SO3 (mass of SO2 (95% efficiency)/MW of SO2 ) x (stoichiometric ratio of SO3 and SO2 based on the second chemical reaction x MW of SO3 mass of SO3 ( 207.77 / 64 ) x (2/2) x 80 mass of SO3 259.71 g ( AT 100 % EFFICIENCY!) mass SO3 (90% efficiency) 259.71 x (90/100) mass of SO3 (90% efficiency) 233.739 g Lastly, by stoichiometric analysis again: calculate for the mass of H2SO4 produced from the third reaction using the mass of SO3 (90% efficiency): mass of H2SO4 (mass of SO3 (90% efficiency)/MW of SO3 ) x (stoichiometric ratio of H2SO4 and SO3 based on the third chemical reaction x MW of H2SO4 mass of H2SO4 ( 233.739 / 80 ) x (1/1) x 98 mass of H2SO4 286.33 g ( AT 100 % EFFICIENCY!) mass H2SO4 (90% efficiency) 286.33 x (90/100) mass of H2SO4 (90% efficiency) 257.70 g answer
- Q:prior to the arrival of Columbus. Is there any evidence for this, or any studies done on this?
- There is evidence of Copper mining - I would contact the Michigan Department of Natural Resources or the State of Michigan Department of Parks and Recreations. Several ancient sites are public parks. They would be able to direct you to more information.
- Q:Iron ore (Fe2O3) is refined to iron (and carbon monoxide) by reacting the iron ore together with coke (pure carbon, C) What mass of coke is required for every 1.000 kg iron ore refined?Steps please.Thanks.
- The smelting reaction is Fe2O3 + 3C 2Fe + 3CO 2 mol of Fe2 requires 3 mol C 1 kg of Fe 17.91 mol and will require 3 / 2 x 17.91 26.86 mol of C or 322.6 g of carbon. Coke (as supplied to a Blast Furnace) is essentially fixed carbon, some ash and moisture and typically 82% fixed C, 13% ash and 5% moisture. Thus the coke equivalent of the above is 322.6 / 0.82 or 0.393 kg So to make 1.000 kg of Fe you need 0.393 kg of coke assuming a iron source of 100% haematite (Fe2O3)
- Q:I need a step by step process, please.
- Plants grow and then die. The dead plants lie in the ground and start to rot. The decaying matter has layer upon layer of soil and dust laid on it over millions of years the pressure and heat builds up turning decaying plant matter into coal. People dig out the coal. The coal is used to fuel furnaces which smelt iron from iron ore. Iron is used to construct bridges.
