Chapter 7 Energy Use in the Copper Industry

Energy Use in the Copper Industry All aspects of copper production require energy, whether i n the form of electricity, explosives, or hydrocarbon fuels (diesel, gasoline, natural gas, fuel oil, coal, coke), or as the energy equivalent of materials consumed (e. g., chemicals and steel grinding media). In 1977, the primary copper in-

Current Energy Requirements in the Copper

20.12.2013  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 mining and mineral concentrating energies are directly proportional to the

Energy and Environmental Profile of the U.S. Mining Industry 5

Copper processing or pyrometallurgical processes employ high-temperature chemical reactions to extract copper from its ores and concentrates. Generally, these processes are used with copper sulfides and, in some cases, high-grade oxides. Depending on the copper mineral and the type of equipment, pyrometallurgical recovery may take as many

Copper Mining and Processing: Processing

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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% ...

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

How copper is made - material, used,

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.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Copper Mining and Extraction Sulfide Ores

The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other countries for processing. For example China, Germany and Japan are major

Energy Consumption in Metal Additive

28.03.2019  The feedstocks used in AM and Machining both involve the same initial process: ore is mined and processed, and then the metal is alloyed and cast into an ingot. The energy consumed in these first steps must be understood to calculate the impact of downstream material waste. Material waste varies widely between manufacturing processes (including AM). We will discuss this further in

Extractive Metallurgy of Copper ScienceDirect

Copper production from recycled end-of-use objects is about 15% of copper-from-ore copper production. Electrochemical processing is always used in producing high-purity copper: electrorefining in the case of pyrometallurgical extraction and electrowinning in the case of hydrometallurgical extraction. The principal final copper product is electrolytic tough pitch copper. It is suitable for nearly all uses.

Mining and metallurgy: The role of filters in

The energy materials are produced from the ground in a reasonably concentrated state, and subsequent processing involves refining with relatively little waste (except perhaps for coal and oil shales – and, as reserves become exhausted, the processing will become more difficult). By contrast, many metallic ores occur naturally mixed with large quantities of unwanted material – gangue – from which they have to be separated: the mineral dressing process
