Nanobubble-Assisted Flotation of Apatite Tailings ...

Processing of materials that originated from tailings of industrial plants (with a wide range of particle size distribution, "PSD") without grinding has several advantages since mines are faced with a lot of pressure to minimize their environmental impacts. This article indicates that the introducti …

Separation of P Phase and Fe Phase in High Phosphorus ...

Experimental Procedure (1) Dissociation of apatite phase and hematite phase by fine grinding. As the grain of apatite phase is so fine and so closely wrapped with the hematite phase in the oolitic high phosphorus iron ore that fine grinding of different levels was adopted to dissociate the apatite phase and hematite phase.

Apatite in fresh rocks has a higher Cl and Mn content, and lower Fe, Mg, Sr, Pb, and calculated X OH-apatite, compared to apatite in altered rocks. The content of F, rare earth elements (REEs), Y, U, Th, and Zr, and the Sr-Nd isotope signatures of apatite from fresh and altered rocks are similar in all apatite grains ( 87 Sr/ 86 Sr = 0.7034–0.7042 vs. 0.7032–0.7043, εNd(t) = 5.3–8.0 vs ...

Production, by co-grinding in a media mill, of porous ...

After 10 h of co-grinding, the particle size reaches 91 µm for mixtures with 30% of apatite, and 63 µm for those including 40% of apatite. The apatite particles are broken during grinding. When the fragments reach a few microns, they adhere to the surface of the polymer particles, preventing agglomeration (see Fig. 5 ).
