Recycling of steel plant mill scale via iron ore

2018-6-13 · Mill scale is an iron oxide waste generated during steelmaking, casting and rolling. Total generation of mill scale at JSWSL is around 150 t/day and contains 60–70%FeO and 30–35%Fe 2 O 3.To recover the iron, the mill scale must be smelted in a blast furnace or other reduction furnace; however, it is usually too fine to use without previous agglomeration such as via pellet or sinter mix.

Closed crucible reduction of lump powdered mill scale

The paper conveys the idea of reducing the mill scale by coal in sequential way on fixed bed (i.e. in crucible) to approach and optimize maximum reduction parameters. As the iron ore also constitutes the similar oxides present in the mill scale, so this approach or methodology will be acceptable for iron ore

Vertical mill simulation applied to iron ores

2015-4-1 · In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuit with a vertical mill. Other three samples of pellet feed had already been tested with the methodology used in this study. The sample of coarse iron ore was characterized in laboratory tests carried out in a small batch ball mill.

2021-4-15 · The sintering process is a pre-treatment phase in the production of iron. Sintering plants are often found in integrated steel mills, where they would recycle iron ore fines from the raw material storage and handling operations and from waste iron oxides from steel plant operations. Iron ore may also be processed in on-site sinter plants.

The Relationship Between Mining and Sintering

The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling
