selective flocculation of low grade iron ore
Performance evaluation for selectivity of the flocculant
Dec 14, 20130183;32;Abstract. Increased demand for iron ore necessitates the utilization of low grade iron ore fines, slimes, and existing tailings. Selective flocculation can be an alternative physico chemical process for utilizing these low grade fines, slimes, and tailings.

However the fines, slimes and tailings generated in the process of beneficiating these low grade iron ores contains good amount of iron values. These iron values can be recovered by further beneficiating the fines, slimes and tailing by selective flocculation, which is defined as the selective agglomeration of iron ore particles using flocculant.
