Introduction
| Arsenopyrite consists of iron, arsen, and sulfur. When the composition of iron is replaced with cobalt, then it forms (Glaucodot,(Co,Fe)AsS).Arsenopyrite has the similar physical properties of marcasite, but these two can be identified according to the different colors, silver and light brass yellow. After weathering, arsenopyrite decomposed as light yellow or light green scorodite(FeAsO4.2H2O) which is the most commonly spread arsenopyrite mineral occurring on the high to mild hydrothermal alternation and also the major source of refined arsen. |
