Understanding the high-grade iron ore market

concentrate, one of the key elements that determines value is its chemical composition, or 'grade'. As a rule of thumb, a higher iron content will generally mean a higher market value for the ore since iron units are what a steel mill wants. But just as important as high iron content is a low level of deleterious impurities such as silica,

Efficient enrichment of iron concentrate from iron ...

12%The iron concentrate grade and iron recovery were relatively low in a shorter roasting time, because the reduction degree of minerals by carbon monoxide was not enough. The prolongation of reaction time would increase the reducibility of iron ore and then heighten the index of magnetic separation concentrate.
