In August 2012 cover story in Bloomberg Businessweek stated that tin mining on the Indonesian island of Bangka was becoming more dangerous and destructive as cassiterite ore deposits became harder to get to. About one-third of all the tin mined in the world has come from Bangka and its sister island Belitung to the east. As tin ore pits become deeper, the number of lethal cave-ins has risen.

tin-mining was undertaken in Cornwall and Devon in prehistoric times and continued into the 20th cent. Early mines exploited alluvial deposits near the surface but by the 16th cent. underground working following veins of ore had become the norm. Flood waters limited access to some tin deposits and deeper mining only became practicable during the 18th cent. when

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called “tin cry” can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium, and frozen mercury. Pure tin after solidifying keeps a mirror-like appearance similar to most metals. However, in most tin alloys
