    May 29, 2020 · Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process."

    Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore

    The iron bloom is formed in the hearth of the furnace. The structure of the iron bloom is sponge-like and it contains some slag. The smelting process ends when the iron bloom gets as big as the breast wall of the furnace so that it can be removed by breaking the breast wall only. This way, the furnace can be used again with a new breast wall
