2015-7-10  Therefore, the direct flotation of iron oxides appears to be more preferable for processing of low grade iron ores containing large quantity of silica and alumina. In any froth flotation process the hydrophobic particles are carried out from pulp zone to froth zone by means of true flotation, but undesirable gangue minerals also report to the concentrate through entrainment and entrapment rather than true flotation.
