WebMimetite is a lead chloride arsenate mineral with the composition Pb 5 (AsO 4) 3 Cl.It is a secondary mineral, formed by oxidation of primary lead minerals in arsenic-bearing lead deposits. It typically forms short hexagonal crystals that are yellow to brown to orange in color, very brittle, moderately hard (Mohs hardness 3.5-4), and dense (specific gravity 7.24). WebDiaphaneity means ability to transmit light. The terms used are: (i) Transparent: When the mineral allows the light to pass through it.
