Hence the mined ore and concentrate contain both these and their decay products in their crystal lattice. Concentration of the tantalum minerals is generally by gravity methods (as with mineral sands), so the latticebound radioisotope impurities if present will report with the concentrate. While this has little radiological significance in the processing plant, tantalum concentrates shipped ...

 · Gangue minerals are detected by ore petrography, XRay Diffraction and Scan Electron Microprobe (SEM) analysis. The most common gangue minerals are aluminous and siliceous minerals, clays (kaolinite, illite), and quartz. When the samples are not characterized for having high level of sulphides, the trace of sulphide phases may be identified by ore petrography. The main iron sulphides mineral ...

 · The niobium–tantalum ore material obtained from Ras Baroud locality in the central Eastern Desert of Egypt, consists mainly of two minerals namely: columbite and alvarolite. The extractive separation of niobium(V) and tantalum(V) from the acid media HF–HNO 3 or HF–H 2 SO 4 have been worked out using methyl isobutyl ketone (MIBK) as an extractant.

commonly found in a number of oxide minerals, often in combination with Columbium ore. This combination is known as "tantalite" when its contents are more than onehalf tantalum. Important sources of tantalite include Australia, Brazil, Canada, China, and several African countries. Synthetic tantalite concentrates produced from tin slags in Thailand, Malaysia, and Brazil are also a ...

process of tantalum in kenticha mine site is gravity separation because of the density difference among the associated mineral or the gangue. Niobium and tantalum are chemically similar and are related to one another in nature which makes it hard to isolate. Basically, the most usable technology for separation of tantalum from the ore is gravity separation, which is the old and .
