Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. Iron ore fines are less desirable (and of lower value) as they need to be sintered before they can be utilised, otherwise it will effectively smother the air flow in the blast furnace.

A Look at the Process of Pelletizing Iron Ore for Steel

A Look at the Process of Pelletizing Iron Ore for Steel

In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning. The mixing step sets the stage for the remainder of the process, creating a homogeneous mixture that will allow for a uniform product to be created. In order to pelletize iron ore fines and/or concentrate, a binder is needed.

Dry Iron Ore Beneficiation Iron Ore Separation ST

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

Iron ore pricing explained Metal Bulletin.com

Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium. Most steel mills use a blend of different grades of ore, and a mix of ...

Mar 09, 2013 The process of sintering is basically a pre-treatment process step during iron making for the production of the charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes (collected dusts, sludge and mill scale etc.).

Usage of High LOI Iron Ore Fines in Pellet Making

Usage of High LOI Iron Ore Fines in Pellet Making

Jun 08, 2019 Loss on ignition (LOI) in the mineral represents the chemically bonded water which can be removed at high temperatures only. High LOI in iron ore fines has an adverse affect during pellet induration process. High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is martite–goethitic and hematite–goethitic form ...
