Investigation of Minerals and Iron Oxide Alterations in

LKAB has been mining and processing iron ore since 1890 and is today the largest European exporter of iron ore pellets. LKAB produces iron ore pellets for two major application areas for use in direct-reduction processes and for iron production via the blast furnace process. In 1996 LKAB built the Experimental Blast Furnace (EBF). The main target was to develop, test and market new blast furnace pellets.

"We look at what is actually picked out of the rock."

What do you do at work? I am a mine geologist in Svappavaara. We work on both planning and production. The main focus is on creating and updating geological models if there is to be blasting in the mine, then we produce models of what can and has to be taken out but we also work a lot on quality control, quite simply following up on what is taken out of the mine and what we send away.

IRON ORE Amazon S3

Minimills do not use iron ore for their feedstock; instead they use iron and steel scrap and some DRI. Net imports of iron ore substitutes at 7.8 Mt were 13% higher than those of 2001. Iron ore substitutes include DRI, iron and steel scrap, pig iron, and semifinished steel. Semifinished steel is produced in the form of blooms, billets, and slabs.

Direct Reduced Iron (DRI) Cargo Handbook the world's

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

Effect of particle size on reduction behavior in iron ore

The reduction of iron ore-coal composite pellets was carried out in the temperature range of 500 ~1200°C by thermogravimetry. This study aims to investigate the effect of particle size of iron ore on reduction behavior. Three samples of different particle size were selected 25 ~48 µm, 75 ~106 µm and 150 ~180 µm. The reaction kinetic parameters were estimated based on the thermogravimetric data.
