why iron ore is crushed with coke Pixis Mining

As Coke is burned in the Blast Furnace it raises the temperature to about 2000°C which is enough to melt the Iron Ore. The Carbon in the Coke chemically reacts with the Oxygen in the Iron Ore to form Carbon Dioxide(CO2, and Carbon Monoxide(CO), which escapes through the Gas Outlet. Limestone.

What Is Iron Ore Sintering? (with pictures)

Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the particles congeal. Once congealed into an agglomerate, the ore is again crushed. Screening ensures non-iron particles are removed and the remaining iron particles average between 15 and 30 millimeters in diameter.

Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified’ or ‘carbonised’ in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.
