Formerly agglomeration was used in a purely physical way, as a process of size enlargement. Fine ore isn''t desired in the blast furnaces, therefor several agglomeration processes were designed, but two of them are used in the iron industries. It called Pelletizing and Sintering.

621· In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
