The Effect of Different Auxiliary Collector in Flotation of Phosphate Ore

Document Type : Research Paper


Flotation is the main technique for extraction of elements from ores with suitable grades. Apatite with the formula of P2O5 can be extracted by flotation method. Fatty acids are the traditional collectors for apatite flotation but they have a poor selectivity against phosphate minerals. So, auxiliary reagents are needed. In this work, we formulated two collector packages with the same fatty acids and Nonylphenol ethoxylated (NPE) as anionic and nonionic surfactants but different in auxiliary reagents, and made a comparison between them in apatite flotation. Auxiliary reagents are polyethylene oxide (PEO) and paraffin. The results indicated that selectivity due to utilize PEO is better but for recovery, using paraffin is suitable.
