- A silver-white or grey ore of arsenic
- Arsenopyrite is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5-6) metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1. When dissolved in nitric acid, it releases elemental sulfur. ...
- A mineral of iron, sulphur, and arsenic commonly associated with metamorphism around igneous intrusions as in the quartz veins of the Meguma Zone of Nova Scotia.
- Is a mineral with the chemical formula FeAsS. Whereas pyrite has S2 subunits, arsenopyrite has AsS units.
- The main ore mineral for arsenic (FeAsS).
- Iron arsenic sulphide, FeAsS
