Selective flotation of apatite from iron oxides

The main difficulty was to reduce the iron content in the apatite concentrate to the level required. Analysis of the QEM∗SEM results for two batch flotation tests gave useful insights into the flotation behaviour of the various types of minerals, particles and composite particles present in the ore. It was found that iron in the concentrate occurred mainly as hematite and goethite, which were collected partly due to the
