Niobium Tantalum Flotation

  • Niobium and tantalum - pubs.er.usgs.gov

    Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...

    Apr 10, 2015  The beneficiation of niobium oxide ores is predominantly carried out by froth flotation, which generally involves niobium mineral flotation at acid pH using a cationic amine collector. In the case of the Niobec and Catalão mines, there is a reverse gangue mineral flotation step prior to niobium flotation.

    Bench-scale flotation tests were carried out on a carbonatite niobium ore sample, and they showed that the reagent combination, at less than 2 kg/t Aero 6493 (hydroxamic acid) and 1.0 kg/t sodium metaphosphate, could recover over 90% of niobium oxide from the ore feed at about 30% mass pull.

    Metallurgical testwork shows that the ferrocolumbite and pyrochlore which host the tantalum and niobium mineralization are amenable to a two-stage process of conventional flotation and proven refining processes with estimated recoveries of 65% to 70%. The first step of the process uses grinding followed by flotation to produce a concentrate.
