How do you purify iron ore? | Yahoo Answers
Sep 16, 2010· Best Answer: This process is an excellent example of purification by reduction of the ore with coke (in fact carbon monoxide does most of the reducing). The ore is heated to about 1500oC by the burning coke into which hot air is pumped. The rocky impurity in the ore reacts with limestone (added to the 'charge') to form a Calcium Silicate slag which floats on the surface of the molten Iron.
