tinbearing

Tinbearing is a geological term used to describe rocks, minerals, or ore bodies that contain tin, most notably the tin oxide mineral cassiterite (SnO2), which is the primary source of tin metal. Tinbearing deposits can form in several geological settings, including granitic and pegmatitic intrusions produced by magmatic differentiation, hydrothermal tin veins associated with granitic stocks, and placer or alluvial deposits where cassiterite grains are concentrated by weathering and transport.

Cassiterite is the dominant tin ore worldwide, though tin can occur in smaller amounts in other minerals

Economically, tinbearing ore is mined, concentrated by gravity methods such as jigs and sluices or by flotation,

Global tin production has been dominated in recent decades by a few major producers, with significant tinbearing
