An Efficient Process in the Production of Iron and Steel from Iron Ore

Abstract

The invention discloses a method of reducing iron oxide to recover iron from iron content mixture. The method includes the step of mixing a reductant containing at least one of a silicon carbide or ferro-silicon with iron content mixture and heating it at a temperature ranging from 600-1000° C. for reaction to undergo. The iron content mixture is one of an iron ore, iron oxide and gangue material. The addition of reductant during the manufacture of sponge iron, DRI or pig iron or during reduction of iron ore assures advantages such as better converts yield, efficient use of resources, thus resulting in increasing productivity and reducing the cost of manufacturing. The method converts and upgrades low grade iron ore to high grade iron ore by dry beneficiation magnetic separation. The method also helps in recovery of iron from slag generated during iron and steel production.

I claim: 
     
         1 . A method of reducing iron oxide to recover iron from iron content mixture, the method comprises step of:
 a. mixing a reductant with iron content mixture where in the reductant has at least one of a silicon carbide or ferro-silicon; and   b. heating the mixture of the reductant and the iron content mixture at a temperature varying from 600° C. to 1000° C. for the reaction to undergo.   
     
     
         2 . The method as claimed in  claim 1  further comprises step of:
 adding a fuel for heating the mixture of reductant and iron content mixture, wherein the fuel includes at least one of a metallurgical coke, coal or any other form of energy used for reduction to-undergo. 
 
     
     
         3 . The method as claimed in  claim 2 , wherein the iron content mixture is one of an iron ore, iron oxide and unwanted gangue materials. 
     
     
         4 . The method as claimed in  claim 3  wherein the iron content mixture is of low grade iron ore then the method further comprises step of:
 dry beneficiation processing magnetic separation, wherein the dry beneficiation processing doesn't need water, which is very efficient and economical, without water requirement.
