1. Introduction. Froth flotation is one of the cornerstones of most mineral processing operations because flotation can efficiently isolate valuable mineral particles diluted in large quantities of unwanted gangue materials .A critical step in flotation is the selective adsorption of hydrophobic collectors onto the surfaces of mineral particles to facilitate particle attachment to air bubbles.While iron removal efficiency was 80.49% for the cyclojet flotation, it was calculated as 75.61% for the conventional cell. These findings showed that cyclojet flotation can be used as an alternative method to conventional flotation for the removal of iron oxides from silica sand.
