EXTRACTION AND SEPARATION OF TANTALUM AND NIOBIUM

The study focused on conditions that affect the digestion of the ore, separation and recovery of tantalum and niobium using 1−octanol and 2−octanol as extractants and their precipitation as oxides and characterization of the final products. The principal minerals of niobium (Nb) and tantalum (Ta) are columbite and tantalite. This, depending on whether the concentration of niobium or ...

01/10/2014  As a result, a flow rate of 1.7 mL/min was selected as the optimum condition to evaluate the total quantitative separation and recovery of Ta and Nb from the other metals in the tantalite ore. Interestingly, a relatively quicker flow rate is the condition which gives better elemental separation results. Normally the longer the time (slower flow rate) the better the separation, but that was not ...

Tantalite - Wikipedia

The mineral group tantalite [(Fe, Mn)Ta2O6] is the primary source of the chemical element tantalum. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite (8.0+ compared to columbite's 5.2). Iron-rich tantalite is the mineral tantalite-(Fe) or ferrotantalite and manganese-rich is tantalite-(Mn) or manganotantalite.
