Effect of Alumina and Magnesia on Microstructure and

The low Al 2 O 3 (2 0 wt%) medium MgO (2 0–2 5 wt%) and high basicity (3 0) sinter showed higher low temperature degradation index (LTD) due to the presence of silico ferrites of calcium and aluminium (SFCA) and magnetite phase and lower pore phase as compared to low basicity iron ore sinter Get price

Effect of alumina and its occurrence on sintering performance

More and more mid-low grade iron ores with high Al 2O 3 content has been exploited and imported from overseas in China Undoubtedly the Alundesired 2O 3 content in iron ores certainly has an adverse impact on subsequent sintering process It is of significant importance to know the sintering performance of -low iron ores with midGet price

effect of alumina on sintering performance of iron ores_

Recent results on pisolitic ore showed that it more readily forms a melt than dense hematite ores 30) Therefore addition of low alumina pisolitic ore such as Yandi to high alumina sinter blends may help to produce more melt and dilute the effect of alumina on sinter quality Get price

Bauxite The principal ore of aluminum

Bauxite is the principal ore of aluminum The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process In the Bayer Process the bauxite is washed in a hot solution of sodium hydroxide which leaches aluminum from the bauxite Get price
