Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is …

1. Washing-classifying-desilting: In the quartz sand beneficiation process, the fine-grained grade with a particle size of less than 0.1 mm is usually called slime.For quartz sand with a large amount of clay and ore mud, as the particle size becomes finer, the grade of silica gradually decreases, while impurities such as iron and aluminum rise instead.
