seperating iron fron tantalite


Tantalum and niobium are always found together, usually in minerals of the tantalite-columbite series in pegmatites, granites, carbonatites and alkaline igneous rocks. Tantalum and niobium are associated with tin-bearing aplite-pegmatite-greisen dykes in northeastern Victoria. The Walwa tinfield, including the Mount Alwa and Bounce mines ...

While this is true, one of the most useful applications of ion exchange for iron removal employs anion exchange resin such as AmberSep™ 21K XLT Resin to capture Fe3+ (ferric) ions as an anionic complex. Similar to zinc, this is possible because these metals form multivalent anionic complexes in the presence of excess chloride ion:

Highlights Tantalite ore was digested using molten ammonium bifluoride. Niobium and tantalum were extracted using octanol as extractant. Addition of H 2 SO 4 improves the separation of niobium and tantalum. Extraction with 2-octanol is almost similar to extraction with 1-octanol. Two and three stages were sufficient for the extraction of Ta and Nb respectively.

Tantalum, niobium, and their oxides are important precursor materials, essential for high-temperature alloys and electronic devices. The primary hydrometallurgical extraction technique to extract tantalum and niobium from minerals involves hydrofluoric acid (HF) digestion of the concentrates, followed by solvent extraction as an oxide separation and purification step.

2. Non-amalgamation of mercury with iron means that the iron is not dissolved, and therefore floats on the surface as a dross. However, non-amalgamation does not mean total insolubility. If a few ppm of iron needs to be removed, washing with a dilute solution of HNO3 might be best, with much agitation. There will be some dissolution of mercury ...
