Is calcium a metal or a mineral? - Quora

Pure Calcium is a metal in the alkaline earth elements family (group 2). It is a metal. Calcium is a soft reactive metal and because it is so reactive, it does not occur in a pure state in nature. Therefore, because it is not naturally occurring, Calcium is not a mineral.

Electrolytic production of calcium metal

The resulting calcium-tin alloy served as the anode for the electrorefining cell, which employed a cacl2-caf2 fused salt as the electrolyte. Calcium metal was electrorefined at 850 deg c with a current efficiency of 85 pct based on calcium metal recovered. The calcium metal analyzed 99.2 pct, which is purer than commercially produced calcium."
