091102 Iron ore
agglomerated iron ores are iron ore pellets which are used as raw material for primary iron and steel making. The stand-alone production of non-agglomerated iron ores and concentrates is not covered by the EU ETS, since the amounts of emissions are too small. The production of iron ore pellets can be described as follows: Non-agglomerated iron …

Iron Ore Sintering: Raw Materials and Granulation
ABSTRACT Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron …

The six main steps of iron ore processing
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
