Solvent Extraction - an overview | ScienceDirect Topics

Solvent extraction has been routinely used for copper refining since its invention in the 1960s, and it is suggested that well over 10% of refined copper production from ores is obtained by solvent extraction, accounting for millions of tonnes of metal. It is even more popular for refining copper from scrap.

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.

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 | Solvay

Solvent extraction Solvay offers a broad range of solvent extractants for purification and concentration of copper, nickel/cobalt, lithium, molybdenum, rare earths and various other metals. Our oxime-based ACORGA® range of copper extractants has a proven track record in the industry and is used by the largest copper producing mines in the world.

Evaluation of Copper Solvent-Extraction Circuit Data and ...

Chemistry of Copper Solvent Extraction Liquid–liquid extraction involves the selective transfer of a substance between two immiscible liquid phases by controlling the relative solubility in each phase. In the case of copper SX, the exchange is typically achieved by an oxime-based chelating mechanism. In particular, mixtures of aldoxime and

Copper recovery using leach/solvent extraction ...

Solvent extraction for copper was not yet proven commer-cially so most copper companies were taking a wait and see attitude. Furthermore LIX 64, the only reagent available, had significant limitations with respect to extractive strength, metal transfer kinetics and copper/iron selectivity and it could

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 - an overview | ScienceDirect Topics

Solvent extraction offers an alternative to ion-exchange resins and activated carbon for concentrating cyanide and copper cyanide. Cyanide recovery by solvent extraction is improved by first complexing cyanide with a metal (as for activated carbon and ion-exchange resins).

Copper - BASF

At the core of BASFs solvent extraction offering is an extensive range of LIX ® oxime extractants that are widely used in the purification of copper leach solutions. Oxime formulations can be tailored to meet individual customer requirements and are suitable for a wide range of leach solutions.
