Sir I need the active support for my Question. In case of Aluminothermic production of ferrotitanium from ilmenite or rutile Aluminium powder is added with lime and mill scale. in case of commercial production purpose we can use stoichemetric ration of Aluminium with ilmenite or rutile. But actual calculation reveals that the amount of Al powder added to ilmenite in the reaction is in the ratio of 100:38( ilmemite: Aluminium). Now for commercial case, the price of Al powder is US$ 3.4 per kg and ilmenite is Us$153 per
1000kg.Plus add the cost of Mill scale, CaO and other Flux materials. Now the minimum Market rate of FeTi(Ferrotitanium 35) is US$ 2.12 per kg. Then how this production process is viable for ferrotitanium commercially. Though a number of companies world wide is using this technique. I think I have made some mistakes anywhere in my calculation. Would You please be kind enough to point out my fault. Plus if you have any better idea regarding this matter please share with us. We would be Highly Obliged. Thanking every body . Amitava dutta- posted
