Copper ore crusher

Copper ore crusher is the crushing plant specially designed for copper ore crushing. Copper ore crushing plant is the key machine since copper ore can only be used if it was processed into powder and copper ore crusher is in the first part of the process. As the hardness of copper ore between 2 and 2.5, NFLG aggregate crushing plant can process the copper ore as easy as turning its hand over.

NFLG copper ore crusher includes jaw crusher , cone crusher , impact crusher , mobile crusher and vertical shaft impact crusher. As to the application, not only can our copper ore crusher process copper ore, but can it also process stones like limestone , sandstone, pebble, basalt, bauxite, marble, gypsum, dolomite, kaolin, iron ore , aggregate, coal and cement, etc. And NFLG copper ore crusher is widely used in cement making industry, building, sand making, metallurgical industry, etc.

Copper ore production

Most copped or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include: Chuquicamata in Chile, Bingham Canyon Mine in Utah and El Chino Mine in New Mexico, US. The average abundance of copper found within crustal rocks is approximately 68 ppm by mass, and 22 ppm by atoms. In 2005, Chile was the top mine producer of copper with at least one-third world share followed by the USA, Indonesia and Peru, reports the British Geological Survey.

Copper ore application
About 98% of all copper ore is used as the metal, taking advantage of distinctive physical properties – being malleable and ductile, a good conductor of both heat and electricity, and being resistant to corrosion.The purity of copper ore is expressed as 4N for 99.99% pure or 7N for 99.99999% pure. The numeral gives the number of nines after the decimal point when expressed as a decimal (e.g. 4N means 0.9999, or 99.99%). Copper ore is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy, and bronze is a copper-tin alloy.

Copper can be machined, although it is usually necessary to use an alloy for intricate parts, such as threaded components, to get good machinability characteristics. Good thermal conduction makes it useful for heatsinks and in heat exchangers. Assorted copper fittings. It is widely used in piping for water supplies, refrigeration and air conditioning.

Copper mining process

There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached.

First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers . Then the ore is crushed and screened, with the fine sulfide ore (<0.5 mm) going to froth flotation cells for recovery of copper. The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution, so the copper can be recovered at a high electrical current efficiency by the electrowinning cells. It does this by adding a chemical reagent to the SX tanks which selectively binds with and extracts the copper, is easily separated from the copper (stripped), recovering as much of the reagent as possible for re-use. The concentrated copper solution is dissolved in sulfuric acid and sent to the electrolytic cells for recovery as copper plates (cathodes). From the copper cathodes, it is manufactured into wire, appliances, etc. that are used in every day life. Below are some photos of the process equipment at an Arizona Copper Mine.

When the copper ore come out from the ground, It is loaded into a 300 ton truck for transport to the crusher. The complete copper crushing plant includes jaw crusher as primary crusher, impact crusher and cone crusher. After crushed, the copper ore must be screened out according to size by screening machine and distribute the classified ore to a series of conveyors, for transportation to the mill for further processing.

In the copper ore grinding process, rod mill, ball mill and regrind ball mill are used. Ball mill is the most common copper ore grinding mill in copper ore concentrator. NFLG can supplies a complete crushing plant for copper mining in Chile, Peru, USA, Congo, Zambia, KZ, Mexico, Belgium, Germany, Zaire, and can also design the special crushing plant according to your requirements.

Copper ore crusher details

Copper is mined either at open pit copper ore mines or underground copper ore mines.

First the copper ore is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.

In the primary crusher, the ore is broken into smaller pieces of less than 25 centimetres in diameter. Crushed ore is then loaded on to a conveyor belt which takes it to the storage bin. In the storage bin, ball mills and other grinding machine grind the ore until it is a fine powder.

During the crushing process,we have improved the capacity and end crushing products with our secondary crusher and tertiary crusher. The total energy consumption is reduced considerably.

Comparing the operation efficiency of CS cone crusher and hydraulic cone crusher, we find CS cone crusher achieved better results in tertiary crushing. And if installing the same number of secondary and tertiary crushers, a part of operation is transmitted from tertiary to secondary crushers where the liner wear is three times less, which significantly influences on the cost reduction in the crushing process.

As a major mining crushing equipment manufacturer in China, we can supply our clients with jaw crusher, cone crusher, impact crusher and industrial grinding mill etc. Our jaw crusher is a good primary crusher, our impact crusher is widely used as secondary crusher, our cone crusher including CS cone crusher, hydraulic cone crusher can be used as secondary crusher and tertiary crusher. Beyond this, we also supply ball mill, vertical mill , Raymond mill , trapezium mill etc. to our clients.

The whole copper ore processing line consists of jaw copper pre crusher, ball copper ore mill, classifier, magnetic separator, flotation machines, thickener, dryers and other major equipments. Aggregate screen , bucket elevator and aggregate feeder can also be used in this copper ore processing.

The whole process of copper ore crusher is that:
Firstly copper ore is exploited from the mine and massive copper ores are delivered to the processing from the copper ore feeder. Copper ore feeder conveys copper ores into the primary copper ore crusher and they get crushed. Then the semi-finished copper ore particles are conveyed by belt conveyor to the secondary copper ore crusher. The products of secondary copper ore crusher can be transported into copper ore mill and get grinded into copper ore powder. Then the copper ore can get processed in chemical treatment.
