iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant highgrade ore is in the form of fine particles, as small as or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Introduction. Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food ...
