Flotation of Hematite Using Oleates as Collectors - AusIMM

Flotation of Hematite Using Oleates as Collectors - AusIMM

Laboratory scale flotation tests were done on mineral hematite and a specular hematite ore using oleic acid and sodium oleate as collectors. The mineral hematite floated strongly in the neutral pH region, with an increased pH range of flotation at higher oleate additions. Concentrates with sufficient hematite grade to meet the paint pigment specification were.
