Copper Recovery by Solvent Extraction Techniques

Since it is common for the copper solvent extraction plant to supply feed electrolyte to an electrowinning plant, it is useful to combine the operating costs for the two plants when comparing costs of copper recovery by solvent extraction techniques with those for cementation.

SX Solvent Extraction of Metals: A Design Manual

Copper Recovery by Solvent Extraction. A common method of copper recovery from oxide ores is dump leaching in which the excavated ore is crushed and dumped on an impervious surface in “lifts” of anything from 10 to 100 ft deep. Sulphuric acid is sprayed onto the levelled off dump via a network of pipes designed to give even distribution.

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 stone that selectively reacts with and binds the copper in the solvent.

Solvent Extraction - an overview | ScienceDirect …

Solvent extraction is a relatively new technology compared to other unit operations such as distillation and absorption. The first large-scale industrial solvent extraction plant was built in 1942 by Mallinckrodt stone Company for production of ton amounts of uranium by selective extraction of uranyl nitrate by ether from aqueous solutions.

The Extraction of Copper - Chemistry LibreTexts

Copper can be extracted from non-sulfide ores by a different process involving 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 by solvent extraction.

Copper recovery using leach/solvent extraction ...

Copper recovery using leach/solvent extraction/electrowinning technology 65 (Figure 2) and a catalytic amount of LIX 63, was introduced in 19657 and in March 1968 the first commercial copper L/SX/EW operation, the Bluebird plan of Ranchers

design and optimization of copper solvent …

At the beginning, copper solvent extraction configuration operating on dilute aqueous phases were constituted with two stages respectively to extraction and stripping steps. Design of this 2Ex2S configuration was simple and based on the value of copper transfer per extractant volume percentage of 0.22 (g/l/1% v/v).
