Niobium Nb and tantalum Ta materials play a central role in the manufacturing of various strategic goods such as electronic components supraconducting magnets military projectiles and high strength low steel alloys [1] This renders the hydrometallurgical processing of Nb and Ta raw materials really challenging Due to their tendency
Hence in the present work Bulk NL structured tantalum is fabricated with distinctive lamellar thickness by processing at room temperature and liquid nitrogen temperature after ECAP The physics behind grain refinement structure features and higher mechanical properties in BCC structured NL tantalum is investigated
Tantalum niobium ore is the main raw material for the production of tantalum but it is often associated with a variety of metal so the main step is the decomposition of tantalum smelting concentrates 0 crushing and screening and modulation post processing if necessary will also increase the magnesium reduction deoxygenation pickling
Niobium Nb and Tantalum Ta are used to increase materials mechanical resistance and produce lighter alloys The worldwide Nb production reached 78 000t in 2020
Processing extraction and refining Cambior Ferroniobium production Rachelle Bergeron The use of columbite and tantalum bearing ores such as tantalite as feedstocks results in the necessity to process these materials chemically as described in the tantalum section The purified niobium containing process stream is generally converted
Tantalum is one of the most inert metals known it is resistant to most acids and corrosion and non toxic to the human body Consequently it is used extensively in the chemical industry for processing equipment and in the medical industry for joint replacements and medical implants
Abstract 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
performing a multi objective technical and economic analysis of tantalum ore processing to increase the production of critical metals minerals The article starts with mineral composition analysis to highlight the potential of strategies for balancing the process layout for maximized production The
Niobium and tantalum extraction industries heavily depend on fluoride chemistry for metal oxide production This study concentrates on developing a fluoride free approach utilizing alkali treatment for selective dissolution of niobium and tantalum phases The application of microwave heating in the alkali treatment of columbite significantly reduced the processing

In Rwanda tantalum exploration is dominated by the high ASM artisanal and small scale mining It is established that tantalum ore is easily accessible and amenable to artisanal extraction and processing techniques This is primarily due to secondary weathering processes affecting the initial tantalum mineralization
As shown in Fig 2 China has the largest number of tantalum processing companies and is a major producer of tantalum based intermediate and final products Most material is exported to other countries in the form of tantalum waste and scrap tantalum intermediate products and tantalum capacitors Fig 11
Very few detailed studies are reported on the hydrometallurgical recovery of niobium and tantalum from their minerals Agulyanski 2004; Ayanda and Adekola 2011; Zhu and Cheng 2011; Nguyen and Lee 2019 Agulyanski 2004 investigated the chemistry of Ta and Nb fluoride based extraction in view of developing new materials for modern applications
