Alacranite

Main Page < Resources < Ore

Alacránite is an arsenic sulfide mineral. It is generally more rare than Realgar and Orpiment. Its origin is hydrothermal. It occurs as subhedral to euhedral tabular orange to pale gray crystals that are transparent to translucent. It has a yellow-orange streak with a hardness of 1.5. It is monoclinic, 2/m. It occurs with Realgar and Uzonite as flattened and prismatic grains up to 0.5 mm across. The solid state properties of disordered realgar. particles induced in alacránite changes by high-energy milling. The crystal structure remained unsolved due to the low diffraction quality of it.
