18-08-2020 Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling ...
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.

Copper is very ductile and can be drawn into very thin wires, which serves as its primary electrical function. It is used for electrical machinery such as motors, electromagnets, generators and communication devices. Copper has been fashioned into ornamental objects and cooking utensils since the beginning of mankind.

10-04-2016 The main copper minerals in Zijinshan copper mine were digenite, covellite and enargite . Experimental work suggests rapid conversion of digenite to secondary covellite in the first stage of copper dissolution, the similar rate of 0.22–0.24 g Cukg − 1 oreday − 1 and the copper extraction reached 15–18% in the first 4 days leaching at both temperatures ( Fig. 4 b, Table 6 ).
01-01-2018 These mineral chemical patterns are reflected in SWIR spectral features, especially those centred around 2250 nm and 2340 nm.
Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification.
Brittle - Mineral crushes to angular fragments (quartz). Malleable - Mineral can be modified in shape without breaking and can be flattened to a thin sheet (copper, gold). Sectile - Mineral can be cut with a knife into thin shavings (talc). Flexible - Mineral bends but doesn't regain its shape once released (selenite, gypsum).
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 copper-red color is almost artificial looking in its fleshy hue.

Historically, copper has also been used as pigments, as it was known to add blue or green colours to minerals like azurite and malachite. This metal was the first to be smelted from its ore (around 5000 BC), the first to be cast into a shape with a mould (around 4000 BC) and the first to be alloyed with tin to create bronze (around 3500 BC).
Because secondary low-temperature processes probably disturb the original copper isotope values of primary copper-rich minerals, in situ determination of copper isotope values for intact mineral grains by microanalytical techniques such as LA-MC-ICP-MS has become increasingly important to understand primary isotope signatures of rock and ore samples.

30-11-2018 Copper is an essential element for human nutrition. The mineral is critical for blood cell formation and is found in many foods and most water supplies. Foods high in copper include leafy greens, grains, potatoes, and beans. Although it takes a lot of copper
Copper, a chemical element that is a reddish, extremely ductile metal and an excellent conductor of electricity and heat. The pure metal is second only to silver in thermal and electric conductivity. Copper is commercially produced mainly by smelting.

Physical Properties of Copper : Cleavage: None : Color: Brown, Copper red, Light pink, Red. Density: 8.94 - 8.95, Average = 8.94 : Diaphaneity: Opaque : Fracture: Hackly - Jagged, torn surfaces, (e.g. fractured metals). Habit: Arborescent - "Tree like" growths of branched systems (e.g. silver). Habit:
The copper isotope ratios of chalcopyrite, secondary malachite, and native copper of metamorphosed Besshi-type volcanogenic massive sulfide (VMS) deposits from two different mines, Japan, were measured by femtosecond-pulsed laser ablation-multiple collector-inductively coupled plasma-mass spectrometry (fs-LA-MC-ICP-MS).
Copper-lead alloys containing about 30% lead are stronger but have less satisfactory surface properties and are usually used with a thin lead-tin overlay. If the copper-lead alloys do not have sufficient load-carrying capacity, the lead content is reduced, and tin is added to improve the strength. Typical is a 74Cu-22Pb-4Sn composite.

The mineral is often found in the form of characteristic pink crusts called "cobalt bloom". Erythrite occurs as a secondary product of cobalt arsenides such as skutterudite ( CoAs 3 ). Nickel may substitute for the cobalt in erythrite to form the mineral annabergite ( Ni 3 (AsO 4 )
The characteristic bluish-green color of the flame is due to the copper. A flame test showing the presence of Lithium . Different flame of Bunsen burner , depending on air flow through the valve:
a. A deficiency sign common to many trace minerals is dermatitis b. The amounts in foods are dependent, in part, on soil composition c. Deficiencies are more difficult to recognize in children than in adults d. The amount of all trace minerals in the average person totals approximately 100 grams e.
