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 The Bright BlueGreen Copper Silicate
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.

Copper-bearing veins that cross-cut the Salobo supergene rocks contain a range of Cu minerals of varying solubility, and these veins commonly include the Cu-silicate mineral chrysocolla. This chrysocolla is often intimately intergrown (10-100 µm scales) with other vein minerals, especially the Cu-phosphate mineral pseudomalachite, and is also intergrown with variably-altered host rock minerals.

Chrysocolla is a bright colored hydrated copper sheet silicate and a minor ore of copper, usually appearing as secondary encrustations on primary copper ores. It is among the brightest of blue and blue-green minerals, accounting for its desirability.

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.
Chrysocolla (hydrated copper silicate) is a mineral and a minor ore of copper, Southern Arizona
Andrew Alden Updated on October 16, 2019 The silicate minerals make up the great majority of rocks. Silicate is a chemical term for the group of a single atom of silicon surrounded by four atoms of oxygen, or SiO 4. They come in the shape of a tetrahedron. 01 of 36 Amphibole (Hornblende)

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.
