controllers in copper extraction controllers in copper extraction (PDF) A monitoring system for the copper solvent extraction. In this paper the current status of the modeling, simulation and control of the copper leaching, solvent extraction and electrowinning process (LX/SX/EW) is...
The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid. The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution ...

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase ...
Copper recovery by solvent extraction has progressed from a technology with limited application for copper recovery from dilute sulfuric acid leach solution to a technology with broad application for copper recovery from a variety of leach solutions. Reagent improvements have led the way, but they ...

In vegetable oil extraction, the principle of solvent extraction is used. A solvent is dissolved in oil fat so as to obtain a mixture of oil and solvent making it possible for oil to be separated from the mixture. Solvent extraction is said to be a mechanical process since .
The process flowsheets involve copper dissolution from the concentrate by pressure leaching in sulphuric acid, followed by purification of the leach liquor by solvent extraction, and metal recovery by electrowinning. The autoclave discharge liquors contain 50 to 90 g/l Cu and, under appropriate operating conditions, minimal residual free acid.
