The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. 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

In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011). In 2010, 770,000 metric tons of copper were recycled, at an estimated value of nearly six billion dollars (Papp, 2010).

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

7. Sulfide Ore Refining. The final step in processing sulfide ore copper from the smelter is to make high purity copper cathodes. 8. Copper Products & Many Uses. Copper cathodes are pure copper produced from the processing of copper ores. However, cathodes are not in the final form of usage as copper materials. 9.

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia ) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is developed for each particular ore, but there are some general trends in the choice of

The flowsheet discussed in this study is for treatment of 100 tons per day oxide-sulfide copper ore by the leaching process using sulfuric acid-ferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment. The flowsheet contemplates a six to seven day leach-wash cycle with one tank being discharged and charged each day.

In the present work, a hydrometallurgical process was developed to recover copper salt from the ore sample. It was demonstrated that the copper incorporated in the ore could be dissolved more than 99%, with the use of dilute sulfuric acid solutions (0.4 M–2.0 M) even under moderate experimental conditions. The activation energy of copper dissolution was calculated to be 2.02 kJ/mol, which

The ore is processed by froth flotation comprising rougher and scavenger cells. The common reagents for copper ore flotation are xanthates as collector, pine oil as frother, sodium cyanide as depressant, and lime to maintain slurry alkalinity.

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.
