Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

copper mining and copper ore extraction knowledge - … Copper Mining and Processing: Processing of Copper Ores . 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
Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Copper Mining in Arizona. The legacy of mining is etched into the landscape and history of Arizona. It is part of the culture, economy, and environment. Indeed, copper is showcased as one of the "Five Cs" upon which the Arizona economy was founded.

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore …
Copper Mining and Extraction Sulfide Ores. These produce many millions of tonnes of copper ore per year. This the processing plant at one of Chile's largest copper mines, El Teniente. . Gold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the.
The bioleaching of sulphide minerals with emphasis on . Millions of tonnes of low grade ore and copper rich tailings await the development of an efficient and economic bioleach process for chalcopyrite (CuFeS 2).The bioleaching of chalcopyrite in situ and in dumps is a practical option only because the low and slow recoveries are countered by the low processing costs (Schnell, 1997).Not ...
The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
Following open pit extraction of ore, the ore is crushed and transported to a leach pad where it is irrigated with a leach solution to dissolve the metal. This image shows surface pools where dissolved copper is extracted from the solution. There are plans underway to use solution mining to extract copper from copper porphyry near Florence.
Mining and Processing Methods. Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production.
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides.The percentage of copper in the actual ore is too low for direct extraction of copper to be viable.
