Bentonite is the most commonly used binder for iron ore pellets. However, due to its high alumina and silica content, the slag volume and energy consumption are increased. The aim of the present work is to identify the CSL (sodium ligninsulfonate added CaCO 3 ) as an alternative binder in iron ore pelletization. FTIR and zeta potential tests verified that …

As high-grade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest cost.
