resource base of mining companies and amount of produced concentrate. As material of tailings dump has already been grinded, separation process requires much less energy and can also decrease total costs of concentrate production. Due to gradual depletion of iron ore reserves, more studies are devoted to tailings processing [3-7]. The

determined. Apatite, ilmenite, quartz, rutile, and zircon are minerals that frequently occur with monazite among other minerals. Hence they were chosen as gangue minerals in this study. The Iso-Electric Point (IEP) of monazite, apatite, ilmenite, quartz, rutile, and zircon are 5.3, 8.7, 3.8, 3.4, 6.3, and 5.1 respectively.

The separation between apatite and carbonate minerals is likely to be challenging for the mining industry due to the surface similarities. A process for the separation of fluorapatite from accompanying carbonate minerals was developed by Kari et al. ( 1987 ) using Resol, Novolak, and melamine-modified Novolak as depressants.
