Paratacamite

Paratacamite

Paratacamite is a mineral composed of copper, hydroxide, and chloride with the chemical formula Cu2(OH)Cl. It is found in layers above other materials and can be stable in acid solutions with aeration and chlorides. It is one of three polymorphs, along with atacamite and botallackite, of basic copper(II) chloride.From: Environmental Effects on Engineered Materials [2018], Optical control of layered nanomaterial generation by pulsed-laser ablation in liquids [2020], The Prehistory of Metallurgy in the British Isles [2017]

In the presence of both aeration and chlorides and in acid solutions the stable form of copper is the chloride paratacamite (CuCl2.3Cu(OH)2). On the whole the rate of corrosion is sensitive to acidity (pH), and aerated acid soils can give quite high corrosion rates.

XRD was applied to explore the compositions of the products in a previous research[31] and the XRD patterns is shown in Figure 7. From the XRD result, we can conclude that the compositions of the green product are paratacamite, atacamite, and nantokite. Therefore, the conductivity of the copper anode decreased because the high electrical resistivity of the green product (paratacamite, atacamite, and nantokite) coverage on the copper anode surface.

According to X-ray diffraction (XRD) analysis of collecting rock samples, the minerals predominantly were detected in copper-bearing units in URF (Table 2). The XRD analysis indicated that paratacamite, atacamite, covellite and chalcocite were identified as major copper minerals and Powellite is the major molybdenum mineral in URF sandstone.
