Ironmaking process - Iron and steelmaking I:
Next, the iron ore, iron ore is also put into blast furnace layer by layer with coke. So it should sustain some burden inside blast furnace. If it could use lump type ore, then it may be okay but in these days the lump ore has been consumed and the available ore is very fine powder type. So these ore is first brought into sinter plants and it under goes some agglomeration process Then we could

Blast Furnace – Official Minecraft Wiki
Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail. Smelting equipment yields one iron or gold nugget from their respective materials. Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace. Fuel is also used at double the rate of

The Ironmaking Process | New Zealand Steel
The New Zealand Steel plant at Glenbrook is unusual in that the huge blast furnaces that dominate the processes at most steel works around the world are not present. This has eventuated because of the nature of the ore mined locally and used in the process. Early pioneering experiments failed to successfully smelt iron from New Zealand's west coast ironsand deposits because the magnetite ore

Steelwork: Tapping of a blast furnace - Sounds
In the blast furnace, liquid pig iron is produced from processed iron ores in a continual smelting process. The blast furnace generates heat of over 2000 degrees Celsius in order to melt iron from the iron ore. To reach this temperature, coke is used as fuel and the fire inside the furnace is fanned with hot air at 1400 degrees Celsius. Also, limestone is added for the purpose of bonding
