The increase of the proportion of high Al 2 O 3 content iron ore fine in iron and steel enterprises has brought about a series of problems such as the increase of the viscosity of blast furnace slag and the difficulty of the separation of slag and iron. In order to solve this problem, the effect of increasing MgO content on the technical and economic …
Understanding Sinter and Sinter Plant Operations. Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pre-treatment step in the production of iron, where fine particles of iron ...
During industrial pilot scale tests conducted in 1000G magnetic field intensity, the obtained Fe grade was 37.45% with 60.23% recovery. The results proved that approximately 61.23% of the slag can be enriched by weight with 37.16% Fe content and can be used 9.0% in the sinter blend by weight as a starter.

Keywords: sinter; MgO; reduction mechanism; melting mechanism; principal component analysis 1. Introduction In recent years, Al2O3 in slag has been improved with an increased imported ore, which is an enormous challenge for blast furnace [1]. To cope with the use of high Al2O3 ores, adding MgO to sinter is considered to be a popular counter ...
Sinter is normally the major component of the blast furnace (BF) charge burden. Sinter consists of many mineral phases produced during process of sintering of iron ores. The quality and properties of sinter are dependent on the mineral structure of sinter. However, since the sintering conditions are usually not uniform throughout the sinter bed ...

The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The …
