Mineralogical Characterization-Assisted Reduction Roasting of Banded
In many parts of India, because of depletion in high grade iron ore, efforts are focused on the use of low-grade iron ore for steel production. As an alternative iron source, low-grade banded iron ores have attracted attention. The beneficiation and utilization of banded iron ore is closely connected to their mineralogical characteristics, nature of impurity inclusion and …

Role of silica and alumina content in the flotation of iron ores
Flotation of banded hematite jasper (BHJ) ore. We have discussed the flotation response of different iron ore minerals based on silica and alumina content. The flotation studies of several samples have indicated that alumina bearing clay is highly detrimental to the recovery of iron values. It is mainly due to the coating of clay particles over ...

Flotation of a South African Low-Grade Banded Iron Formation (BIF)
Due to declining iron ore grades, low-grade ores with complex mineralogy, namely, banded iron formation (BIF), are being explored to maximize iron ore resources and increase the life of mine. Flotation is the standard global process used for the beneficiation of BIF ores, as it is a complex ore reserve, and liberation is typically achieved below 1 mm. This study focuses on …
