Chalcanthite is water a soluble Copper Sulfate mineral having rich blue or green color. It is usually found in copper deposits in the later stage of oxidation. Since it gets dissolved easily, it is more frequently found in dry areas. This pentahydrate is the most widespread member of the family of analogous hydrated sulfates, the chalcanthite.
Derivation of Name
Roughly translated from Greek, Chalcanthite implies a copper flower. Appropriate names for this striking mineral are "copper vitriol" and also "blue stone."
In nature, the mineral chalcanthite exists in dry caves and arid areas which cannot attract water. It often forms botryoidal (An external appearance of a cluster of grape) and stalactite growths along the ceilings and walls of mine tunnels due oxidation of copper sulfide minerals.
Chalcanthite is a superb stone for the throat chakra. It is believed that this stone aids in meeting your expectations through the mode of communication. Besides, this stone helps one to live a happy and pleasant life, without feelings of being lonely. Chalcanthite or copper sulfate is prone to moisture and humidity and as such, it is important to preserve it in an atmosphere away from an environment of moisture, so that the crystal structure does not get ruptured. We find it in nature in dry regions. Several specimens are developed in the laboratories.
Chalcanthite does not exist in great quantities in moist regions. However, the ore of chalcanthite occurs in abundance in dry regions like Chile. Any ground water rich in sulfate, that at any time, leaches out copper occurring from other minerals of copper, will on vaporizing, crystallize into chalcanthite. In several copper mines, chalcanthite continues precipitating and forms blue encrustations,
Being a copper mineral, chalcanthite may be utilized as a copper ore. This is among the few sulfate minerals that are soluble in water. Because of its solubility property, it may crystallize, dissolve and recrystallize repeatedly before its deposit gets exposed. . It gets created in the secondary oxidation of the surface closer to zone of copper deposits. Solutions of copper sulfates have a lot of chemical applications. These solutions and crystals of copper sulfate are essentially found in chemistry labs.
