The average energy per tonne of ore, per ounce of gold, per tonne of copper, and per tonne of copper equivalent can all be used to calculate the remaining energy requirement. Using the average of all three methods, the annual comminution energy consumption for the mining of copper and gold is approximately 44 terawatt hours.
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.

Energy and Environmental Profile of the U.S. Mining Industry 5 Copper ... 5.1 Process Overview 5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New ... Crushing and grinding is the most energy intensive.
cubic yard of copper ore of density 4,500 lbs, a value of 1,929 J/metric ton (1.849 x 106 Btu/ton of cathode copper) was calculated. This is about 9.2% of the total energy used in mining. The energy used for loading operations depends on loading conditions, equipment used, and the nature of the rock.
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. 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 flowsheet in this study is designed to get the maximum recovery from a large tonnage of porphyry copper ore. The Copper Process Flowsheet Copper Ore Crushing. The crushing section consists of three-stage ore reduction with either a grizzly or vibrating screen between each crushing stage.
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago.
Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.
energy used in crushing copper ores - dojokunvda.it. what is the copper ore crushing process - … what is the copper ore crushing process. ... Grinding and concentration together consume about 45 percent of the energy used in the pro- duction of cathode copper.
The current trends in copper processing are towards methods and equipment that use less energy and produce less air pollution and solid waste. In the United States, this is a difficult assignment because of the stringent environmental controls and the very low-concentration copper ores that are available.

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 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.
Within an ore, copper concentration is commonly less than 1%. Each of the different natural forms of copper requires distinct mining and processing steps that eventually lead to 9.99% pure copper. C. Historical and Modern Copper Use The development of copper has a rich history. Copper has been used for thousands of years; it may
