Note: zinc carbonate –  a group of minerals that are combinations of zinc and silica, carbon and oxygen. They occur where water and oxygen have acted on a mineral made up of zinc and sulfur.  “Carbonates” can be highly enriched.  Around the turn of the century they were referred to as “calamine”  what is now known to be a mixture of smithsonite, zinc carbonate and hemimorphite – zinc silicate.
