Effects of Pretreatments on the Zeta Potential
The effects of pretreatments on the zeta potential characteristics of hematite were investigated on a number of hematite samples. The bulk of the test work was conducted on a sample of naturally occurring hematite from the Iron Prince deposit in the Middleback Range area of South Australia. The iep of the ROM ore was measured as 2.6, which was only slightly raised by ultrasonic cleaning.

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.
