Recovery of copper from alkaline glycine leach solution

A variety of solvent extraction reagents have been investigated for the recovery of copper ions from pregnant leach solutions. Oxi-mes and b-diketone extractants have been extensively studied and applied commercially in the extraction of copper from acidic and alkaline aqueous solutions [1,2,19,21,26,31]. The oximes do have

Development of copper recovery process from flotation

Jun 15, 2018· Therefore, this research aims to develop a copper recovery process from flotation tailings using high‒pressure leaching (HPL) followed by solvent extraction. Over 94.4% copper was dissolved from the sample (CuFeS 2 as main copper mineral) by HPL in a H 2 O media in the presence of pyrite, whereas the iron was co‒dissolved with copper

The solvent extraction separation of molybdenum and copper

Aug 01, 1995· An optimum pH of 1.9 was determined for copper extraction. From loaded solvent, this metal is easily stripped with copper-containing concentrate sulfuric acid solutions to give a pregnant solution suitable for final recovery of metal by electrolysis. Keywords Molybdenum, copper, solvent extraction, extractive metallurgy, molybdenite, leaching.

US4039405A Leaching copper ores and solvent extraction

This invention relates to a process whereby recovery of copper from copper ores using leaching and solvent extraction techniques can be increased. The process generally comprises leaching to obtain a pregnant leach liquor, washing ore residues with an extra quantity of water to obtain extra dissolved copper values, recovering said copper values, combining the extra wash water with the pregnant

Copper Solvent Extraction & electro-extraction

Leaching is the process by which the processing of oxidized copper ores is carried out. Diluted sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. The leaching solution called “pregnant” (or pregnant liquor) is then treated using a solvent extraction and electro-extraction or SX-EW process.

Solvent extraction and electrowinning Wikipedia

Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes using an
