What is a Copper Anode? (with picture)
· Copper anodes differ from these in that they are used specifically for copper refining in a process referred to as copper smelting. A copper anode is made from pulverizing a copper ore called chalcopyrite, CuFeS 2 , and mixing it with water, pine oil and amyl xanthate, a salt used to make the mixture water-repelling.

Copper Ore Types: Sulfides versus Oxides
Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is ...
Copper Mining and Processing: Resources and Glossary ...
For copper sulfide ore, electrolysis is the final stage in the process of pyrometallurgy, in which anode copper slabs are hung in a large tank full of a copper-based electrolyte solution and an electric current is applied, resulting in the plating of copper onto 99.9% pure copper cathodes.

Chalcopyrite.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
World Copper Production at a Glance
Copper is an essential component in many of the products that make up the world around us. Ductility, malleability, and superior conductivity of heat and electricity, are just a few of the properties that make this unique metal so useful across a broad range of applications.
Copper Mining Process | Information | New Mexico | Basics
Other types of ore are treated by solution extraction-electrowinning, commonly referred to as SX/EW. The copper ore is placed in large “leach” stockpiles and the copper is leached from the rock by applying dilute acidic solutions to the stockpile. This copper-bearing solution is captured and sent to a SX/EW plant where the copper is ...
The first tin alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC.After 600 BC, pure metallic tin was produced. Pewter, which is an alloy of 85–90% tin with the remainder commonly consisting of copper, antimony, and lead, was used for flatware from the Bronze Age until the 20th century. In modern times, tin is used in many alloys, most notably tin/lead ...
Copper, Silver and Gold
The blister copper is then dissolved in H 2 SO 4, which can be made from the gases evolved in roasting and reduction, and the solution electrolyzed to produce cathodes of pure electrolytic copper. Gold and silver are usually recovered from the electrolysis sludge, and help the economics of the process.
Copper Acetate, Carbonate, Chloride, Oxide, Sulfate ...
Copper sulfides are the major copper ore, and after separation from iron and other unwanted material, these are roasted to produce the oxide. Copper oxide is then converted to blister copper through heating, and further purified through electrorefining.
Copper anodes are placed alternatively with refined copper sheets in a tank through which a copper sulfate solution and sulfuric acid are circulated. A low voltage current is then introduced, causing copper to transfer from anodes to the pure copper sheets, producing 99.9% copper cathodes.
