    Abstract: Tantalum is recovered from an impure source containing niobium, tungsten, titanium, iron, and other impurities by a process comprising mixing the impure source with an alkali metal carbonate, drying the resulting mixture, heating the dried mixture to convert the tungsten to a soluble form, leaching to solubilize the tungsten, digesting the resulting leached solids containing tantalum in hydrochloric acid to solubilize iron values and a portion of the titanium values, dissolving the leached solids containing tantalum values in hydrofluoric acid, adjusting the pH of the resulting solution to form a first tantalum precipitate, dissolving the first tantalum precipitate in oxalic acid adjusting the pH to form a second tantalum precipitate, dissolving and digesting the second tantalum precipitate in hydrochloric acid solution to form a third tantalum precipitate of high purity.

    Abstract: Disclosed herein is a method for producing potassium fluorotantalate crystals, comprising heating, to 60null C. or higher, a starting solution prepared by adding hydrofluoric acid and hydrochloric acid, and, if necessary, water to a highly pure tantalum solution, adding potassium chloride to this starting solution, and cooling the mixture to 40null C. or lower at a cooling rate of less than 15null C./h to precipitate potassium fluorotantalate crystals, wherein the concentration of the hydrofluoric acid in the starting solution is not more than 20% by weight. By this method, highly pure, large-sized potassium fluorotantalate crystals can successfully be obtained in high yield. Moreover, disadvantages to equipment and operation in the prior art can be overcome to a significant extent with this method.

The above metal oxides may also be utilized in combination with alumina and silica. The fluorocarbon partial pressure in the treatment vapor may be in the range of from about 0.001 to about 100 atmosphere. By the practice of the instant invention high surface area metal fluoride extrudates are prepared by the conversion of metal oxide extrudate, particularly aluminum fluoride extrudates from alumina extrudates.
