A Look at the Process of Pelletizing Iron Ore for Steel ...

Preparing Iron Ore For PelletizingThe Pelletizing ProcessThe Process Development Behind Iron Ore PelletizingConclusionIron 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. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials 在feeco上查看更多信息

Pellet Process Uses and Exposures May 2010 - The Iron Platform

Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material) are known collectively as the "burden".
