Tin APEX Mineral

Tin (Sn #50) (Latin: Stannum) is the next element on the periodic table for my APEX mineral collection.

Tin Minerals - There are many Tin minerals.  
Cassiterite (SnO2)[Tin Oxide] with 79% Tin is the obvious APEX Mineral.
Tin has a very low melting point and resists oxidation.  Tin supplies are limited.  It has had some unique global trade regulations leading to price fixing.
Tin was first used in the Bronze Age to produce bronze (copper and tin alloy).
Tin is primarily used in solder and tin-plating where low toxicity is required.
Tin plays no natural biological role.
