Ore Sintering - an overview | ScienceDirect Topics

4/2/2010 · The “ore group” iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The Ore Group scheme defines ...

Slag - Wikipedia

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

Airway inflammation in iron ore miners exposed to dust and ...

The aim of the present study was to investigate if underground miners exposed to dust and diesel exhaust in an iron ore mine would show signs of airway inflammation as reflected in induced sputum. In total, 22 miners were studied, once after a holiday of at least 2 weeks and the second time after 3 months of regular work. Control subjects were 21 “white-collar” workers. All subjects ...

Iron Ore - an overview | ScienceDirect Topics

The sintering process, which has become an important part of the overall ironmaking process, was initially developed because of iron ore in dust form. Using sinter reduces waste and makes the ironmaking process more efficient ( UK Steel, 2014 ), and lessens the amount of raw fluxing stone required in the process.

Chapter 82 - Metal Processing and Metal Working Industry

During pyrometallic processing, an ore, after being beneficiated (concentrated by crushing, grinding, floating and drying), is sintered or roasted (calcined) with other materials such as baghouse dust and flux. The concentrate is then smelted, or melted, in a blast furnace in order to fuse the desired metals into an impure molten bullion.
