Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given in 1801, and niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in 1950. Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

and Tantalum during the mineral processing. This project searches the use of improved fast and flexible fine tuning production processes control based on new software models and advanced sensing. It is expected to increase the recovering in 7-12% on the current best production processes and increase energy saving on a
The shifting of tantalum production to the DRC, Rwanda and other African nations raised the concerns about tantalum's status as a conflict mineral. Conflict minerals, as defined by the SEC and Dodd-Frank Act, include the metals tantalum, tin, and tungsten.
Today, the market for tantalum is supported by the growth in consumer electronics, aerospace, medical, military, energy and chemical processing. Sources The primary source of tantalum is from minerals such as tantalite, columbite, wodginite and microlite contained in pegmatite ore bodies.
Tantalum was mined for many years until its closure in 2012 by previous owner GAM. Tantalum and lithium are both located within a series of mostly flat to shallow-dipping pegmatites. Mineral Resources purchased the Wodgina deposit, tenements and associated infrastructure from GAM in late 2016, with GAM retaining the tantalum rights.
Tantalum Mining Process. The tantalum concentrate is transported to the processor for chemical processing. The concentrate is then treated with a mixture of hydrofluoric and sulphuric acids at high temperatures. This causes the tantalum and niobium to dissolve …

Abstract. The extraction of niobium and tantalum from two tantalum-niobium ore materials obtained from Mozambique, using a combination of magnetic separation, acid leaching, solvent extraction and ion exchange methods was investigated.
This paper presents a brief review of extractive metallurgy of tantalum starting from processing of its ore to two pure intermediates K 2 TaF 7 and Ta 2 O 5 and their conversion to pure tantalum metal by various technically feasible processes. Though tantalum metal can be produced by several means only two processes - sodium reduction of K 2 TaF 7 and fused salt electrolysis of K 2 …

Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl(Si2O 5) 2, lepidolite K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl(SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.
MINING AND PROCESSING : Tantalum is produced by the processing and refining of its ore tantalite. Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum.
AB Gold envisions to change the current value proposition for the gold mining industry of Africa by transforming the gold ores into higher value-added products directly in-country. Sooner, AB Gold will a mining exploration company with a focus on building a leading gold acquisition and development company in Africa and globally.
Tantalum-niobium ores are mostly placer ores with simple properties and single composition. Generally, the content of mud is high and the clay is strong. JXSC has had great success with tantalum-niobium mines in Nigeria, Rwanda and Uganda. We provide them with a full set of tantalum-niobium ore beneficiation processes, equipment, and ...
Tantalum and niobium minerals almost invariably contain low levels of the radioactive elements uranium and thorium. These elements remain in the processing residues but are not present in the processed product. In the case of the FeNbTa alloy, processing is undertaken in Brazil and the residues remain with Taboca.
