Copper extraction

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be ...

The Extraction of Copper

The Process The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). ...

Mining and Refining – Process

The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240°C the pressure is approximately 3.5 MPa. The slurry is then cooled in a series of flash tanks to around 106°C at atmospheric pressure and by flashing off steam.

Copper

Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation).A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings and the ...

12.3: Metals and Ores

Bronze, an alloy of copper and tin has been in use since ancient times. The Bronze Age saw the increased use of metals rather than stone for weapons, tools, and decorative objects. Brass, an alloy of copper and zinc, is widely used in musical instruments like the trumpet and trombone.

The monument is made from bronze (copper and tin), but the bronze figure at the top (Spirit of Freedom) is gilded with gold foil. The Chemistry of Patination The first step in the development of a patina is oxidation to form copper (I) oxide (Cu 2 O), which has a red or pink colour (equation 1), when copper atoms initially react with oxygen molecules in the air.

Tin was used for nearly everything that copper, pewter, brass, or silver could be used for, but generally did not last as long. Reviewing tin catalogs from about 1870 reveals that tin was used for far more than cookie cutters—it was used to make children''s toys, coffeepots, lunch boxes, and …

Innovations: Copper: Technology & Standards

The early U.S. copper industry, located primarily in the American West (Arizona, Utah, New Mexico, Montana, and Alaska) was restricted to mining very rich copper-containing minerals. The introduction of the flotation process in the late nineteenth century permitted the extraction of copper and other metals (including gold and silver) from low-grade porphyry ores.

How copper is made

Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began. The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States.

Copper

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another ...

The Ancient History of Copper

 · The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.

Current Energy Requirements in the Copper Producing …

 · In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the "recovery efficiency" of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the "recovery efficiency," with a typical mining operation requiring about 20 million Btu/ton of cathode copper produced.
