industrial copper solvent extraction process

Copperextractionrefers to the methods used to obtaincopperfrom its ores.The conversion ofcopperconsists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

A two level control strategy that stabilizes and optimizes the production of anindustrialcoppersolventextractionprocessis presented. The stabilizing layer consists of a multi-input-multi ...

Liquid-liquidextraction(LLE), also known assolventextractionand partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organicsolvent(non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Solventextractionprocessconclusion Advantages ofCopperSolventExtraction. Compared with cementation,solventextractionhas considerable advantages. First of all, typical operating costs for a combinedsolventextractionelectrowinning operation can be as low as $30/ton ofcopperfor the larger capacity plants.

Coppercan be extracted from non-sulfide ores by a differentprocessinvolving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution bysolventextraction.

The leaching,solventextractionand electrowinning (LX-SX-EW)processis a widely used method in the production ofcopperfrom low-grade oxidized ore.Copperis the most common metal to be processed by LX-SX-EW, but theprocesscan also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

MetalsolventextractionFrom thecoppermines of Chile to mining sites across the world, we have developed global expertise for choosing the right fluid to effectively extract valuable metals. Escaid™ hydrocarbon diluents are used as diluents for thesolventextractionof minerals includingcopper, nickel, cobalt, uranium and zinc.

A mathematical modeling method was developed by the Bureau of Mines for the prediction of the principal equilibrium species in thesolventextractionofcopper. The use of models for predicting the amount of metal extracted can reduce the amount of experimental work required to characterize a system for purposes such as optimization studies.

Thecopperand nickel remain In solution. Thecopperissolventextracted. The types ofsolventused in thisprocessare organic ones such as oximes, diethyldithiocarbamate, butyl acetates and ketoximes. Thesesolventsform organometallic chelates with the metallic species in question, in this casecopper, which are soluble in the organic phase.

Copperprocessing is a complicatedprocessthat begins with mining of the ore (less than 1%copper) and ends with sheets of 99.99% purecoppercalled cathodes, which will ultimately be made into products for everyday use.The most common types of ore,copperoxide andcoppersulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Chapter 6CopperProduction Technology The last boomin technological innovation for thecopperindustry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyrycopperores.

Design of this 2Ex1S configuration was based on the expected value ofcopperextractionefficiency of 90%. MacCabe Thiele method was introduced in design ofcoppersolventextractionconfiguration whencoppersolventextractiontechnology started to be used for high-gradecopperore.

Extractionofcopperfrom ammoniacal solutions with LIX 84 and LIX 54 used alone and their mixture was studied, and a chemical model was proposed and verified. The equilibriumextractionconstant was correlated with the ionic strength. The effect is weak for the strong extractant LIX 84 and its mixture but very strong for the weak extractant LIX 54. LIX 54 acts as a modifier of LIX 84 by ...
