Azurite is a copper carbonate hydroxide mineral with a chemical composition of Cu 3 (CO 3) 2 (OH) 2. It is best known for its characteristic deep blue to violetblue color. The blue color, known as "azure," is like the deep blue evening skies often seen above deserts and winter landscapes.
Copper is a malleable, ductile reddish metal, and is one of only two strongly colored metals (gold being the other). Copper is a stable metal largely unaffected by water and air, although carbon dioxide will react with the surface of pure copper to form greenish copper carbonate.
4/24/2019· Which characteristic of minerals may be described using words such as "bladed," "fibrous," "platy," or "dendritic"? A. Streak B. Crystal habit C. Lattice framework D. Luster
Distinguishing Characteristic: Conductive Origin of your Samples: Timmins, Ontario Other Occurrences: Chile, Peru, Mexico, Europe, South Africa and USA Uses: Chalcopyrite is the primary ore of copper. Copper is used in electrical wires, plumbing pipes, coins, kitchen appliances – just to name a few.
Mineral Mineral Hardness: Hardness (H) is the resistance of a mineral to scratching. It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardness. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
7/3/2019· Copper(II) burns green in a flame test. Copper''s atomic symbol Cu is derived from the Latin term ''cuprum'' meaning ''metal of Cyprus''. Copper sulfate compounds are used to prevent fungus and algae growth in standing water supplies such as ponds and fountains. Copper is a redorange metal that darkens to a brown color as it is exposed to air.
Copperlead alloys containing about 30% lead are stronger but have less satisfactory surface properties and are usually used with a thin leadtin overlay. If the copperlead alloys do not have sufficient loadcarrying capacity, the lead content is reduced, and tin is added to improve the strength. Typical is a 74Cu22Pb4Sn composite.
What Are the Five Characteristics of a Mineral. Minerals are solid naturally occurring inorganic compounds that possess an orderly internal structure and a regular chemical composition A mineral species has to possess these five characteristics to be regarded as scientifically valid The first and most basic characteristic of
The interlocking Copper and Silver masses that are commonly found in the Keweenaw Peninsula are known as "Halfbreeds". Some Copper on the mineral market has been cleaned and shined using various solvents. These forms are Copper can easily be spotted as their copperred color is almost artificial looking in its fleshy hue.
Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c

Mineral Mineral Carbonates: The carbonate minerals contain the anionic complex (CO3)2–, which is triangular in its coordination—, with a carbon atom at the centre and an oxygen atom at each of the corners of an equilateral triangle. These anionic groups are strongly bonded individual units and do not share oxygen atoms with one another.
Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity.
Mineral Crystals: The beautiful purple crystals in the photo above are examples of amethyst, a purple color variety of quartz. These amethyst crystals grew in a cavity below the earth and because they grew in an open space they were able to form into sixsided prisms with pointed terminations. The prismatic habit is characteristic of amethyst.

Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures (figure 9). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous.
Color should be considered when identifying a mineral, but should never be used as the major identifying characteristic. Streak. Streak is the color of the powdered mineral, which is usually more useful for identification than the color of the whole mineral sample. Rubbing the mineral on a streak plate will produce a streak.
Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper

Phytogenous and hepatogenous factors influence secondary chronic copper poisoning. Phytogenous chronic poisoning is seen after ingestion of plants, such as subterranean clover (Trifolium subterraneum), that produce a mineral imbalance and result in excessive copper plants that are not hepatotoxic contain normal amounts of copper and low levels of molybdenum.
