2 天前  Copper and Its Modern Applications. Copper is a mineral by definition because it is a native element on Earth. Its applications range from practical/utilitarian to decorative/ornamental. It efficiently conducts electricity, so it is frequently used in wiring. Copper is also made into alloys with other metals.

2019-3-10  Definition of Copper. In its free-occurring metallic state, copper was probably the first metal to be used by humans. Neolithic people are believed to have used copper as a substitute for stone by 8000 BCE. Around 4000 BCE, Egyptians cast copper in molds. By 3500 BCE, copper began to be alloyed with tin to produce bronze.

However, hydroxy-chlorides, sul-fates, arsenates, phosphates, vanadates and silicates may be locally common and even of economic importance.

Whether gold remains in porphyry copper deposits is important both to their economic attractiveness and to the distribution of gold in the upper crust. Cu/Au atomic ratios of porphyry copper ore deposits form a continuous range from about 5000 to 5,000,000 with a median near 40,000, which separates gold-rich and gold-poor deposits.

All minerals weather, but sulphide minerals tend to weather much faster than many other minerals. They also contain large quantities of metals which can be harmful to our health and the environment, among others copper, cadmium and lead. When sulphide minerals weather, acidic metallic leach water occurs, Acid Mine Drainage, or AMD.

The primary copper minerals include chalcocite, digenite and some bornite. The host rock to mineralization is a medium- to coarse-textured porphyritic andesite and/or dioritic to microdioritic dikes. Five lithological units are found in the Don Gabriel deposit area, all of which are upper members of the Quebrada Marquesa Formation.
