Minerals and Meteorites and Other Geology Stuff DIOPTASE (Hydrated Copper Silicate) crystals
Toussaint determined the DTA of several copper silicate minerals including dioptase and suggested the mineral contained water only and not OH units. Rozinova and Muratov determined the TG and DTA of a wide range of copper containing minerals and concluded that the product of the thermal decomposition was tenorite. Kiseleva.

Copper silicate is a compound containing copper, silicon, and oxygen atoms. It's a blue-green or turquoise-colored material that's insoluble in water. The copper ions in the compound provide its distinctive coloration, characteristic of many copper-containing compounds.

Copper dissolves in silicate melts (natural magmas) dominantly as Cu 1+ and perhaps in very minor amounts as Cu 2+.Copper is believed to dissolve in silicate melts mainly as CuO 0.5.The solubility of Cu in sulfur-free silicate melts increases with increasing temperature and increasing oxygen fugacity (Liu et al. 2015 and references therein). Zajacz et al. (2012, 2013) also suggest that Cu.

Obviously, in these copper minerals, it can be found that the order of 65 Cu enrichment is Cu silicates > Cu carbonates > Cu sulfates > Cu oxide > native Cu > Cu sulfides. Compared with native Cu, Cu sulfides have lower 65 Cu/ 63 Cu by about 0.5-1.1‰ at 25 °C, while Cu silicates, Cu carbonates, Cu sulfates, and Cu oxide have higher 65 Cu/ 63 Cu by about 2.8-3.4‰, 2.3‰, 1.9‰, and 0.7.

Chrysocolla, a silicate mineral, hydrated copper silicate, CuSiO3·2H2O, formed as a decomposition product of copper minerals in most copper mines, especially in arid regions. It occurs as crusts or masses in the upper parts of copper ore veins where the copper minerals have been altered by water

Copper-bearing silicate minerals are relatively resistant to hydrometallurgical leaching. More efficient extraction of this residual Cu requires detailed knowledge of the mineralogical and textural settings of the minerals, which we outline in this study. Supergene oxidation and alteration of Fe-rich rocks at the Salobo iron-oxide copper-gold.

Copper silicate mineral chrysocolla Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. [1] [2] [3] In mineralogy, silica (silicon dioxide, SiO2) is usually considered a silicate mineral.

Nanosized copper silicates with three different structural morphology (amorphous, nanotubes and MEL) were prepared using different synthesis methods. The physico-chemical properties of copper silicates were characterized by XRD, FT-IR, SEM, HRTEM, N 2 -physisorption, XPS and H 2 -TPR techniques. The results indicated that the preparation.

Chrysocolla (hydrated copper silicate) is a mineral and a minor ore of copper, Southern Arizona
Kinoite ( Ca 2 Cu 2 Si 3 O 8( OH)4 [2] [3] or Ca2Cu2Si3O10 · 2 H 2 O [4]) is a light blue copper silicate mineral. It is somewhat scarce. It has a monoclinic crystal system, vitreous luster, and is transparent to translucent. It can be found in the Santa Rita Mountains, the Christmas Mine at Christmas, Arizona and a few other copper mines.
