DYSCRASITE (Silver Antimony) - Amethyst Galleries

Dyscrasite is actually an alloy of the silver and antimony which means the atoms of silver and antimony are combined with metallic bonds instead of ionic or covalent bonds. Alloys are usually placed in the Elements Class. But dyscrasite is placed in the Sulfide Class because antimony is really a semi-metal and not a metal like silver.

Lead processing | Britannica.com

Of the more than 60 known lead-containing minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore.

Antimony tends to concentrate in sulfide ores along with copper, lead and silver. It occurs sparingly as a free element, but when it does it is usually in association with arsenic, bismuth or silver. The principal ore minerals of antimony are stibnite and jamesonite, but it can also be a byproduct of certain other minerals.
