difference between iron ore and coal mining

Raw materials Steel production. 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 1000-1100C in the absence of oxygen for 12-36 hours. Jan 12, 2021 Longwall mining involves underground coal mining, whereby a long wall of coal is mined via a single slice, and the slice is usually from two feet to a little over three feet thick. The block of coal being mined, which is called the longwall panel, is normally approximately 270 to 430 yards in width and two to three miles in length.
