Tantalum in the environment ScienceDirect
Tantalite (Fe,Mn)Ta 2 O 6 is the most important mineral for tantalum extraction. Due to lanthanide contraction and hence their similar properties, niobium and tantalum replace each other isomorphically in minerals. Tantalite has the same mineral structure as columbite (Fe,Mn)Nb 2 O 6 and both are commonly found together.Tantalum and niobium are extracted from a variety of minerals and concentrates. The major source of niobium and tantalum is columbite-tantalite, also called coltan, with a general chemical formula (Fe,Mn)(Nb,Ta) 2 O 6.The two elements also exist in more than 150 other minerals and are usually present as complex metal oxides and Beneficiation of Niobium and Tantalum from Tantalite Ore

Tantalite: The mineral columbite-tantalite information and
The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite-(Fe) (also known as Ferrotantalite), and Tantalite-(Mn) (also known as Manganotantalite) being used for this mineral's IMA-accepted nomenclature.Ferrotantalite is always dark and opaque; Manganotantalite is usually reddish-brown and may exhibit Tantalum is largely used in applications that require increased chemical, corrosion, and/or heat resistance. Roughly half of the tantalum is consumed by the electronics industry, primarily to manufacture capacitors (for electronic products such as cellular phones and computers) and sputtering targets. The remainder is consumed by Tantalum American Geosciences Institute

Recovery of niobium and tantalum by solvent extraction from Sn–Ta–Nb
Hydrofluoric acid is normally used in combination with sulphuric acid for the digestion of tantalum and niobium concentrate, 15 yielding the binary system that is used as leaching solution in this work. Previous laboratory studies carried out by the authors 16 (see Table S1†), concluded that the best conditions for the leaching of the slag in the binary acid Electronic Industry. Tantalum is widely used in the electronic industry for various applications. It is used to produce tantalum alloys, which possess excellent mechanical strength and corrosion resistance.

Mineralogical characterization and comprehensive utilization
3.1 Main physical and chemical properties of ore 3.1.1 Chemical analysis of ore. Chemical multi-element analysis results of the ore used in the present work are presented in Table 1.The contents of Nb 2 O 5 and Ta 2 O 5 in the ore are 0.013 wt% and 0.011 wt%, respectively; these grades satisfy the requirements of the relevant industries. The aim of this study was to evaluate the use of different fluoride salts, namely NH 4 FHF, KF, KFHF, CaF 2, NaF and NaFHF as fluxes for the dissolution of a Ta/Nb mineral sample originating from Mozambique. Results obtained at optimum experimental conditions for each fluoride flux were then compared with those obtained Comparative study of tantalite dissolution using different

A new technology for processing niobite ore found in Jiangxi
A new process is proposed for refining niobite ore that is found in Jiangxi province of China. Niobite, also known as columbite or niobite–tantalite, is a mineral that contains tantalum and niobium.The separation process includes two-stage grinding, gravity concentration, magnetic separation, and flotation.The tantalum/niobium concentrate Columbite-tantalite minerals are potentially useful for dating the emplacement age of economically important rare-element pegmatites. Romer and Wright have shown that columbite-tantalite may accommodate considerable amounts of uranium (circa 500–1000 ppm) and exclude lead almost completely.The U-Pb systematics, U-Pb columbite-tantalite chronology of rare-element
