Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc uses range from metal products to rubber and medicines. Zinc alloys readily with other metals and is chemically active. On exposure to air, it develops a thin gray oxide film (patina), which inhibits deeper oxidation (corrosion) of the metal.

Stibnite (Sb2S3) is the predominant ore mineral of antimony. Antimony compounds help prevent skin burns, increase battery life, and refine glass used for cellphones. A surprising 83% of antimony consumed stateside is imported—mostly from China—leaving the US susceptible to supply disruption.
