Tin is most often produced from the mineral cassiterite, which is made up of about 80% tin. Most tin is found in alluvial deposits, riverbeds, and former riverbeds, as a result of erosion of ore bodies containing the metal. China and Indonesia are currently the world's largest producers.

For two years no long-term contract for tin ore was negotiated. The smelter, the only source of refined tin in the United States, produced 50 percent of the tin used by United States consumers in 1952. By 1953 the Texas City smelter was able to handle all grades of tin from pure alluvial to low-grade primary ore.

Tin, tungsten, fluorite, and precious stones were important foreign exchange earners in the early 1980s and so, to a lesser extent, was antimony. Minerals of substantial value to the domestic economy included lignite, gypsum, salt (which was also exported), iron ore, lead, manganese, limestone, and marble.

Cassiterite is by far the most important tin ore, although small amounts of tin are recovered from sulphide minerals such as stannite (Cu2FeSnS4) but they are more difficult to process. Primary deposits can occur within the granite or within pegmatities or aplites (dyke like rocks) associated with the granite. They occur also in rocks ...

Tin is a soft, malleable, ductile and highly crystalline silvery-white metal.When a bar of tin is bent, a crackling sound known as the "tin cry" can be heard from the twinning of the crystals.Tin melts at low temperatures of about 232 °C (450 °F), the lowest in group 14.

Bolivia, however, did not sign the ITC's International Tin Agreements in the 1970s and 1980s. In 1983 Bolivia joined the newly formed Association of Tin Producing Countries, which attempted—unsuccessfully—to control tin prices through a cartel approach to commodity regulation. After a period of decline, tin prices rebounded in the late 1980s.

As tin ore pits become deeper, the number of lethal cave-ins has risen. Approximately one tin miner a week was killed in Indonesia in 2011 — double the number of the year before.
