This tantalum-filament bulb is a fabulous curiosity for an element collector such as myself. I had no idea tantalum was ever used in lamp filaments, and in fact it was only used for a few years ending in 1910, so these bulbs are very rare. (See this website for pictures and information about nearly every tantalum lamp ever made. According to .
GK Home > GK Blog > Manganese Mining and Processing: Everything you Need to Know From the tools used to the progress of mining technology, manganese mining has evolved from primitive methods to a highly advanced, technology-based process that allows us to achieve a substantial increase in manganese production.
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.
Solvent extraction developments in southern africa. The first commercial process using solvent extraction for the refining of the platinum-group met- als was in South . the recovery of copper, cobalt, nickel, tantalum, and niobium. Key words: . the first plants .
Manganese processing, preparation of the ore for use in various products. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such
Production of raw materials. Extraction or production of tantalum raw materials of all kinds is widespread, whether by primary industrial mining, artisanal mining, as a secondary mineral or as a by-product. Brazil is currently the major producer. Significant quantities are also produced in China, the DR Congo, Russia and Rwanda.
3 • Raw materials like minerals form the basis for all industrial production processes and are therefore vital for industry. • In a few regions of the world, there is a risk that funds obtained from the extraction of raw materials could be used to finance armed conflicts. • In the attempt to sever the connection between raw material extraction and the
The technique of leaching niobium and tantalum from a low-grade niobium–tantalum ore by highly concentrated caustic potash solution is under development, and there is a general lack of information. The present work mainly focuses on the leaching behaviour of niobium, tantalum and other associated impurities in the low-grade niobium–tantalum .
Tantalite is the principal ore of tantalum. Tantalum has a symbol of Ta, melting point of 3,020 °C and a boiling point of 5,457 °C. . Tantalite which is rich in Manganese, characterized by its brown and translucent nature, and is known as tantalite-(Mn) . To extract tantalum from tantalite at the mine site, the mineral is first crushed .

The Congo is a major producer of many metals aside from tantalum, including tin and cobalt, but for over a decade the extraction of these resources has been linked to conflict, human rights abuses .
In order to separate tantalum and manganese, a solvent extraction process was conducted. In the solvent extraction experiment, the concentrations of Ta and Mn were diluted to 1000 mg/L and 150 mg/L, respectively. . Critical Raw Materials for the EU: Report of the Ad-Hoc Working Group on Defining Critical Raw Materials.
Almost all known kinds of tantalum raw materials used in extraction of tantalum and niobium known in the production scale until now contain a large amount of natural uranium the form of U 3 O 8 —a natural mixture of uranium (4) and uranium (6). Sometimes the uranium content in the raw materials containing tantalum-niobium is higher than 0.5%.

An oxide layer which forms on the surface of tantalum can act as an insulating (dielectric) layer. Because tantalum can be used to coat other metals with a very thin layer, a high capacitance can be achieved in a small volume. This makes tantalum capacitors attractive for portable electronics such as mobile phones.
