Nov 20, 2008  Among the gangue minerals, one of the main problems is the carbonates occurring either as small inclusions or veinlets within apatite or as free grains. The presence of carbonates (dolomite, calcite) may cause problems in apatite concentration by froth flotation due to the poor selectivity of the apatite in relation to these gangue minerals ...

Apatite - Wikipedia

Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH , F and Cl ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2. The mineral was named apatite by the German geologist Abraham Gottlob W

Mar 17, 2021  Brannerite, UTi2O6, is the most common of the refractory uranium minerals and requires leaching under intense conditions to effectively extract the uranium contained within. Brannerite is often found together with apatite in metasomatic uranium deposits. Apatite and other phosphate gangue minerals can inhibit uranium leaching by generating phosphate ions which interfere with the reactions ...
