2021-1-15  Tin comes from the mineral cassiterite, SnO 2, with artisanal mining mostly in Bolivia, Brazil, China, Indonesia, Myanmar, and to a lesser extent in DRC and Rwanda (Barume et al., 2016). Tungsten occurs as the mineral wolframite, [(Fe, Mn) WO 4], with ASM in China and some in Colombia, DRC, and Rwanda.

ITRI Artisanal and Small Scale Mining Policy

2018-2-5  Tin is produced from the mineral cassiterite (SnO2), a tin ore containing various impurities which are removed during concentration, smelting or refining. Cassiterite occurs in deep hard rock mines and in near surface deposits (alluvial and eluvial). Extraction of the mineral can often be carried out effectively with simple tools and low investment thus providing opportunities for production via ASM. Such artisanal operations have

Cassiterite Ore – TSL Mining. Cassiterite is a tin oxide mineral, SnO₂. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite was the chief tin ore throughout ancient history and remains the most important source of tin today.
