Iron ore pelletizing systems

Iron ore can be upgraded to a higher iron ore content through beneficiation This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being.

The Making of Iron & Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

Pig iron

Pig iron is an intermediate product of the iron industry, also known as crude iron, which is obtained by smelting iron ore in a blast furnacePig iron has a very high carbon content, typically 38-47%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications The traditional shape of the molds used.
