The present paper reports the flocculation of iron ore slimes from Joda mines of TISCO and Kiriburu mines of SAIL situated in the west Singhbhum district of Bihar, India. These two slimes had marginal difference in density. The presence of clay minerals was in case of Joda slimes. The settling rate following flocculation was measured as function of time.
Selective flocculation studies on iron ore minerals . By S Subramanian and KA Natarajan. Abstract. Selective flocculation was studied for binary combinations of artificial mixtures of hematite, corundum, and quartz and on a ternary system containing hematite, corundum, and quartz by using starch as the selective flocculant. The important.

In many mineral processing applications it is necessary to know the isoelectric points of the various minerals in the ore to properly perform flotation and other mineral separations. However, current zeta potential analysis technology used to determine the isoelectric point of a particle suspension cannot deliver the isoelectric point of each individual mineral, just an average of the mineral.

The hydrophobic flocculation method uses the hydrophobic interaction between the hydrophobic particles suspended in water to attract each other and aggregate them, and then separate them. This method can increase the grade of the original ore from less than 10 at the beginning to 40 to 50 , and greatly increase the efficiency of recycling to.

Jun 08, 2015 Iron ore is one of the most important ores in the world. Over the past century, most mining of iron ore has been focused on magnetite (Fe3O4). As the name suggests, magnetite is magnetic in nature and is easily separated from gangue (unwanted) minerals through magnetic separation processes. Unfortunately, the magnetite ore bodies are diminishing.
In order to ensure iron concentrate grade and iron recovery, a large number of processing reagents are selected and applied in the iron ore beneficiation. The process water carried plenty of residual processing reagents, and such wastewater with color depth and strong smell could seriously affect the environment and the local people.
