the apatite iron ores in Northern Sweden was early noticed and investigated in some detail in the 1960's2. The samples then consisted of gangue minerals from different ores, flotation concentrates of apatite and handpicked apatite grains. These results

Characterization of phosphate rocks. Characterization studies of phosphate rock (PR) samples should provide data on: (i) the composition of the apatite, other phosphate minerals and gangue minerals; (ii) the relative amounts of mineral species present (estimated); and (iii) the particle size of the various minerals in the rock fabric, etc.
mineral was pulverized and sized with Tyler screens. The minus 65 plus 100 mesh (201 to 147 microns) size fraction was subjected to a series of magnetic and gravity separations to remove the gangue minerals. The presence of verv faint apatite lines in the r-ray powder diffraction pattern

carbonates, as mineral gangue, the Belcina Th-Y mineralization could be attributed to a carbothermal process more than to a hydrothermal one. Key words: thorite, thorogummite, xenotime-(Y), Nb-rutile, monazite-(Ce), brabantite, apatite,
The density of gangue minerals is mainly distributed in the range of <3.1 g/cm 3, among which 2.5–2.7 g/cm 3 is the greatest portion. The characterization study results show that although the particle size of the slime is ultra-fine, the liberation of apatite is good, and the density of most gangue mineral particles is lower than apatite.

A method is disclosed for beneficiating a fluorspar concentrate containing apatite as a gangue mineral, which includes further concentrating the fluorspar by a froth flotation process wherein the apatite is collected and floated with a cationic reagent in an acid flotation …
In favorable circumstances, what would otherwise be gangue minerals (quartz, potassium feldspar, albite, and muscovite) can be mined along with lithium and (or) tantalum as coproducts. Most LCT pegmatites are hosted in metamorphosed supracrustal rocks in the upper greenschist to lower amphibolite facies.

Abstract. Gangue minerals from hydrothermal deposits (apatite and carbonates) and their host rocks from three different volcanic areas (SE Spain, La Serena and Melipilla in Coastal Range of Chile) have been studied for broad elemental compositions.
The highest Schulz efficiency of separation (recovery of apatite minus recovery of gangue) was achieved at ≈51.0 mN/m. The critical surface tension of wettability (y C) of apatite was found to occur at 34.7 mN/m when determined by means of gamma flotation experiments, and it was 33.9 mN/m when determined by Zisman's approach.

studies indicated that ilmenite, magnetite and apatite are main valuable minerals. The gangue minerals consist of the silicate minerals such as pyroxene, olivine, plagioclase and some secondary minerals. Ilmenite in Qara-aghaj ore occurs in three forms: ilmenite grains, exsolved
