Effect of 25% Goethite on the Hydrophobicity and Oleate ,
Flotation tests conducted on the two Iron Duke samples using oleate showed that the presence of goethite adversely affected the flotation response of the hematite but contact angle measurements showed a higher hydrophobicity for the sample containing 25% goethite Correcting the oleate addition for the changes in surface area still showed that the goethite reduced the flotability of the hematite
