Hydrometallurgical Copper Extraction

The successful development of the Cyprus Copper Process has been an evolutionary series of events covering a time span of some seven years. What does the Cyprus Copper Process do? Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications. This ...

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of ...

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy. Hydrometallurgy is typically divided into three general areas:

06-09-2020· Hydrometallurgical extraction accounts for about 4.5 million tonnes of cathode copper per year (about 20% of total primary copper production). Most of this is produced by heap leaching.

Especially for copper and cobalt, solvent extractions are already established unit operations. For the extraction of copper, oximes are the most common extractants. For the extraction of cobalt from sulfate solutions, phosphonic acids are used. In this work, the usage of solvent extraction for copper and cobalt is investigated. 10, 16, 17

Secondary sulfides – those formed by supergene secondary enrichment – are resistant (refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalc…

This method is a hydrometallurgical alternative to chalcopyrite smelter technology and eliminates sulfur dioxide emission problems with its associated costs. Batch testing at 900 C with the chalcopyrite-ferric sulfate system resulted in copper extraction exceeding 99 pct. At an optimal energy consumption of 1,520 kW· hjst, 95 pct of the copper

In this work, a hydrometallurgical stepwise method, involving leaching in a ZnCl 2 –NH 4 Cl solution system, copper removal by ECS method, deep purification with zinc powder, and zinc electrowinning, was investigated and applied for the disposal of zinc-and‑copper-bearing solid waste slag generated by smelting process of waste brass.
