Solvent Extraction Training SX Course

Solvent extraction, the process of extracting a specific metal valve from a solution to concentrate and purify that metal is a multistage process involving liquid ion exchange. In the first stage the metal value, in this example copper, exists in the aqueous leachate as an copper ion. The aqueous leachate is mixed with a organic solution containing a ion specific extractant.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

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.

Non-Sulphide Ores - Copper

Three different stages are involved when extracting copper from non-sulphide ores. 1. Over a very long time and on a vast scale, the reaction of the ore with a dilute acid (such as dilute sulphuric acid) produces an extremely dilute copper sulphate by solvent extraction.
