Background Artisanal mining of cassiterite is one tedious activity that is done daily. It involves daily extraction of economic mineral deposits through the use of primitive tools like shovel, digger, and spade. The continuous extractive act by these artisanal miners tends not to bother the Government of Nigeria and as such, there is no …

Cassiterite (SnO 2) is the most common tin ore mineral, and it is often found alongside other minerals.Magmatic, hydrothermal, and/or replacement processes produce primary tin deposits. Weathering of primary deposits, followed by movement and deposition of the resultant sediments in a new environment, results in secondary deposits.

The Bolivian tin belt is a metallogenic province in the Eastern Cordillera of the Andes known for its Sn, W, Ag, and base metal deposits. Cassiterite, which is a major constituent in many magmatic-hydrothermal ore deposits from the Bolivian tin belt, can incorporate dozens of elements within its crystal lattice, making it a useful geological …

Although Myanmar was a major tin and tungsten producer pre-World War II, since the 1960s much of its mining industry has been an essentially artisanal operation, in 2013 representing less than 0.1% of the country's GDP (Gardiner et al., 2014). This emergence of Myanmar is a potential "Black Swan" event in tin production – an event …
