\Cal"a*mine\ (k[a^]l"[.a]*m[imac]n or -m[i^]n), n. [F.
calamine, LL. calamina, fr. L. Cadmia. See {Cadmia}.] (min.)
A mineral, the hydrous silicate of zinc.
Note: The name was formerly applied to both the carbonate and
      silicate of zinc each of which is valuabic as an ore;
      but it is now usually restricted to the latter, the
      former being called smithsonite.
