Sphalerite: Mineral information, data and localities.

Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).

Zinc also re­acts with oth­er sub­stances: halo­gens, oxy­gen, chalco­gens, al­ka­lis, acids, am­mo­ni­um and am­mo­nia salts, and also with weak­er met­als. Zinc does not re­act with ni­tro­gen, and is an amor­phic met­al. In re­ac­tions with al­ka­lis, the el­e­ment forms com­plex com­pounds – hy­droxo-zin­cates.
