Cu2AsO4OH
Cu2AsO4OH is a mineral that belongs to the phosphate-arsenate group. Its chemical formula indicates it is a copper arsenate hydroxide. This mineral is known for its distinct crystalline structure and specific physical properties. It typically occurs in oxidized zones of copper and arsenic-bearing hydrothermal deposits. The color of Cu2AsO4OH can range from green to bluish-green, and it often exhibits a vitreous luster. It is a relatively rare mineral, and significant deposits are not commonly found. Its hardness is typically around 3 to 3.5 on the Mohs scale, and it has a specific gravity of approximately 4.3 to 4.5. Cu2AsO4OH is not a widely used industrial mineral, and its primary significance is in mineralogy and geological studies. It can be mistaken for other copper minerals, so careful analysis is required for positive identification. The presence of both copper and arsenic in its composition necessitates caution regarding its handling due to the potential toxicity of arsenic compounds.
