Nigeria is endowed with vast but largely untapped solid mineral resources including tin ores (cassiterite and stannite). Tin, which is one of the oldest metals known to man, is invaluable in a wide variety of uses due to its intrinsic properties such as great malleability and ductility, low melting point, softness, corrosion resistance, non-toxicity, anti-friction qualities, and …
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides.However, tantalite has a much greater specific gravity than columbite (8.0+ …

Tantalite ore is produced from a deeply weathered pegmatite regolith and from adjacent eluvial deposits. Initial focus at Kenticha was tantalum, with historical production for 27 consecutive years from 1990-2017 producing between 100tpa-200tpa of tantalum concentrate containing 50% to 70% tantalum pentoxide (total run-of-mine to date is 5.3Mt).
The activities of the artisanals and small-scale miners in Nasarawa state, Nigeria, are increasing daily without considering the loss of biodiversity, which has continuously disrupted ecological functions and environmental balance. The study aimed at investigating the effect of tantalite mining activities on flora diversity.
Values in Fig. 1 exclude production or tantalum contained in tin slags. Tantalum is also produced in Thailand and Malaysia as a by-product of tin mining. This source represented 13% of total tantalum production in 2010 (Talens Peiró et al., 2013).Interestingly, tantalum has been the subject of a study on mineral supply chain …
Tantalite was discovered at the location in 1901 by brothers Francis and William Michell, who subsequently mined 70 tonnes of the ore between 1905-1909. A company called Tantalite Ltd formed by Lady Deborah V Hackett-Moulden and N.S. Young then mined the site between 1925 to 1943, exporting tantalite ore concentrate mainly to the United States.
Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.

The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), 'tantalite' or 'coltan' are not scientific names, yet they are widely used. Many specimens commonly named tantalite are actually minerals of the columbite or tapiolite group ...
