Jan 12, 2020 · The iron is poured into the stacks along with coke (carbon-rich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. The sintering process forms pieces of ore that are 10-25mm, and these pieces are then mixed with coke and limestone.
