Cassiterite (SnO 2) is the main ore mineral of tin in magmatic–hydrothermal tin deposits, but tin transport and precipitation mechanisms from hydrothermal fluids remain poorly understood.We critically evaluated aqueous tin speciation in hydrothermal fluids from extensive experimental data and thermodynamic modeling.
Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek …
