Extraction Stripping LO BO PLS LE Raff RE Fig. 1. General flow diagram of the copper solvent extraction process. The copper transfer between the aqueous and organic phases takes place in mixers and the phases are separated in settlers. The equipment used for the solvent extraction process varies considerably. For
stage, copper ions are selectively moved from the aqueous phase to the organic phase by means of an organic extraction chemical in an organic solvent. The coppercontaining loaded organic solution is washed with water to remove impurities. In the stripping stage, copper ions are moved from the
phase 5, rich with metallic copper, is lead to stripping mixer 6, where it is mixed with the stripping solution,, the strong acid/weak electrolyte, then in the settler 8 the copper is A. M. Spasic et al. Solvent Extraction and Entrainment Problem 167
ore is transformed mainly into elemental sulphur if, for example, ferric or cupric chloride are used as lixiviants12. The Role of Solvent Extraction in Copper Hydrometallurgy Solvent extraction offers the means to upgrade leach liquors for the production of pure electrolytes.
30/09/1999 · In an acid leach copper extraction circuit for leaching copper values from copper ores using a waterimmiscible organic solvent solution containing a copper extractant and an acid strip solution, the improvement wherein the stripped organic solvent solution is contacted with copperfree fresh aqueous acid to remove additional copper values therefrom, and then the resulting super stripped ...
During the prestripping, a total of 192 million tons of material was removed, including waste, sulfide ore and oxide ore. It resulted in over 710,000 tons of sulfide ore in stockpiles ready for processing and 33 million tons of copper oxide ores for potential use in the future. When production begins, the Sierra Gorda mine will process daily 110,000 tons of ore, producing
Copper and its salts such as copper oxide are important products with wide appliions in the chemical and other allied industries. To this end, the extracted/stripped product containing pure copper obtained from the solvent extraction step (involving precipitation and stripping for the enrichment of

18/09/2015 · Copper processing is a complied process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called hodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and ...
The extraction behavior of Cu(II) ions from a real sulfate liquor obtained from the heap leaching stage of a copper oxide ore was investigated using a chelating reagent, Chemorex CP150 in kerosene. A comparative study was also carried out on the extraction capability of Cu(II) ions using other solvents including D2EHPA and Cyanex CP150 demonstrated an effective and selective ...
25/01/2018 · To remain competitive, the domestic metals industry must not only make advances in mining methods, but also in ore processing. One processing advancement under investigation is the development of nonconventional solvent extraction (SX) stripping techniques such as hydrogen, hydrolytic, and precipitation stripping.

McCabeThiele constructions for (a) extraction and (b) stripping of copper in the hightenor SX circuit (32 vol.% Acorga M5774 in Shellsol 2325).
Central African Copper belt involves four stages – namely, leaching, separation, solvent extraction, and electrowinning. The preferred choice for processing ores from the democratic republic of congo (DRC) and Zambia is agitated leaching. Agitated leaching involves reacting coppercontaining ore with acid in an agitated tank.
