The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process. Escondida in Chile is the biggest copper producer in the world, accounting for 5% of global production.
Copper mining and refining provides over 10,000 jobs in Arizona. According to the Arizona Mining Association, the combined direct and indirect impact of copper mining was worth up to $34.2 Billion in the U.S. economy and 12.1 billion in Arizona.
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. The conversion of copper consists of a series of chemical, physical, and electrochemical processes.
Copper Smelting Industry Description and Practices Copper can be produced either pyrometallur-gically or hydrometallurgically. The hydromet- ... refining processes result in copper and SO. 2. emis-sions. Emissions of arsine, hydrogen vapors, and acid mists are associated with electrorefining.
The integrated mining, smelting and refining facilities operated by KGHM Polska Miedz SA (KGHM) ranked as the world's sixth largest refined copper supplier, and the third largest source of silver in 2005.
refining is the reduction of the copper and oxygen removal by feeding a reducing gas such as ammonia, reformed gas, or natural gas into the copper while it is still in the anode furnace.
According to statistics from the International Copper Study Group (ICSG), in 2014 the world's 20 largest copper refineries had a combined capacity of over 10 million metric tons or over 35 percent of total world copper refining capacity. Four of the five largest refineries - and 10 of the top 20 ...
The Oxygen Flash Furnace At the Asarco copper smelter in Hayden, Arizona, the oxygen flash furnace is initially heated up with natural gas. It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux.

The copper mining process: from the ground to cathode. Environmental Effects The way in which copper has been traditionally mined has resulted in the production of toxic waste products and negative changes to the immediate mine environment.
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.
